Working with Tables in Word document

17 Dec 202424 minutes to read

A table in Word document is used to arrange document content in rows and columns. WTable instance represents a table in Word document. A table must contain at least one row.

1. A row is a collection of cells and it is represented by an instance of WTableRow. Each row must contain at least one cell.
2. A cell can contain one or more paragraphs and tables. An instance of WTableCell represents a table cell. Each table cell must contain at least one paragraph.

NOTE

Adding more than 63 columns not supported in Word document using Microsoft Word application. It shows alert when you attempt to insert table with more than 64 columns, which is a one of the behaviors of Microsoft Word and Essential® DocIO does the same.

The following image illustrates how a table in Word document is organized in EssentialDocIO’s DOM:

The following code example illustrates how to create a simple table with predefined number of rows and cells.

Nested Table

You can create a nested table by adding a new table into a cell. The following code example illustrates how to add a table into a cell.

C# [Cross-platform]

//Creates an instance of WordDocument class
WordDocument document = new WordDocument();
IWSection section = document.AddSection();
section.AddParagraph().AppendText("Price Details");
IWTable table = section.AddTable();
table.ResetCells(3, 2);
table[0, 0].AddParagraph().AppendText("Item");
table[0, 1].AddParagraph().AppendText("Price($)");
table[1, 0].AddParagraph().AppendText("Items with same price");
//Adds a nested table into the cell (second row, first cell).
IWTable nestTable = table[1, 0].AddTable();
//Creates the specified number of rows and columns to nested table
nestTable.ResetCells(3, 1);
//Accesses the instance of the nested table cell (first row, first cell)
WTableCell nestedCell = nestTable.Rows[0].Cells[0];
//Specifies the width of the nested cell
nestedCell.Width = 200;
//Adds the content into nested cell
nestedCell.AddParagraph().AppendText("Apple");
//Accesses the instance of the nested table cell (second row, first cell)
nestedCell = nestTable.Rows[1].Cells[0];
//Specifies the width of the nested cell
nestedCell.Width = 200;
//Adds the content into nested cell
nestedCell.AddParagraph().AppendText("Orange");
//Accesses the instance of the nested table cell (third row, first cell)

//Specifies the width of the nested cell
nestedCell.Width = 200;
//Adds the content into nested cell
nestedCell.AddParagraph().AppendText("Mango");
//Accesses the instance of the cell (second row, second cell)

Align text within a table

You can iterate the cells within a table and align text for each cell. Find more information about iterating the cells from here

The following code example illustrates how to align text within a table.

C# [Windows-specific]

private void AlignCellContent(WTableCell tableCell, VerticalAlignment verticalAlignment, HorizontalAlignment horizontalAlignment)
{
    //Sets vertical alignment to the cell.
    tableCell.CellFormat.VerticalAlignment = verticalAlignment;
    //Iterates body items in table cell and set horizontal alignment.
    AlignCellContentForTextBody(tableCell, horizontalAlignment);
}
private void AlignCellContentForTextBody(WTextBody textBody, HorizontalAlignment horizontalAlignment)
{
    for (int i = 0; i < textBody.ChildEntities.Count; i++)
    {
        //IEntity is the basic unit in DocIO DOM. 
        //Accesses the body items as IEntity
        IEntity bodyItemEntity = textBody.ChildEntities[i];
        //A Text body has 3 types of elements - Paragraph, Table and Block Content Control
        //Decides the element type by using EntityType
        switch (bodyItemEntity.EntityType)
        {
            case EntityType.Paragraph:
                WParagraph paragraph = bodyItemEntity as WParagraph;
                //Sets horizontal alignment for paragraph.
                paragraph.ParagraphFormat.HorizontalAlignment = horizontalAlignment;
                break;
            case EntityType.Table:
                //Table is a collection of rows and cells
                //Iterates through table's DOM and set horizontal alignment.
                AlignCellContentForTable(bodyItemEntity as WTable, horizontalAlignment);
                break;
            case EntityType.BlockContentControl:
                BlockContentControl blockContentControl = bodyItemEntity as BlockContentControl;
                //Iterates to the body items of Block Content Control and set horizontal alignment.
                AlignCellContentForTextBody(blockContentControl.TextBody, horizontalAlignment);
                break;
        }
    }
}
private void AlignCellContentForTable(WTable table, Syncfusion.DocIO.DLS.HorizontalAlignment horizontalAlignment)
{
    //Iterates the row collection in a table
    foreach (WTableRow row in table.Rows)
    {
        //Iterates the cell collection in a table row
        foreach (WTableCell cell in row.Cells)
        {
            //Iterate items in cell and set horizontal alignment
            AlignCellContentForTextBody(cell, horizontalAlignment);
        }
    }
}

Insert Image to Table Cell

You can insert an image into the table cell by accessing the paragraph in that cell. The following code example illustrates how to insert an image into a table cell.

C# [Cross-platform]

//Creates an instance of the WordDocument class.
using (WordDocument document = new WordDocument())
{
    IWSection section = document.AddSection();
    //Adds a new table into the Word document.
    IWTable table = section.AddTable();
    //Specifies the total number of rows & columns.
    table.ResetCells(2, 2);
    table[0, 0].AddParagraph().AppendText("Product Name");
    table[0, 1].AddParagraph().AppendText("Product Image");
    table[1, 0].AddParagraph().AppendText("Apple Juice");
    //Adds the image into the cell.
    FileStream imageStream = new FileStream(@"Image.png", FileMode.Open, FileAccess.ReadWrite);
    IWPicture picture = table[1, 1].AddParagraph().AppendPicture(imageStream);
    picture.Height = 75;
    picture.Width = 60;
    //Saves the Word document to MemoryStream
    MemoryStream stream = new MemoryStream();
    document.Save(stream, FormatType.Docx);
    //Closes the Word document
    document.Close();
}

C# [Windows-specific]

//Creates an instance of WordDocument class.
using (WordDocument document = new WordDocument())
{
    IWSection section = document.AddSection();
    //Adds a new table into the Word document.
    IWTable table = section.AddTable();
    //Specifies the total number of rows & columns.
    table.ResetCells(2, 2);
    table[0, 0].AddParagraph().AppendText("Product Name");
    table[0, 1].AddParagraph().AppendText("Product Image");
    table[1, 0].AddParagraph().AppendText("Apple Juice");
    //Adds the image into the cell.
    IWPicture picture = table[1, 1].AddParagraph().AppendPicture(Image.FromFile("Image.png"));
    picture.Height = 75;
    picture.Width = 60;
    //Saves the Word document.
    document.Save("Sample.docx", FormatType.Docx);
}

VB.NET [Windows-specific]

'Creates an instance of the WordDocument class.
Using document As New WordDocument()
    Dim section As IWSection = document.AddSection()
    'Adds a new table into the Word document.
    Dim table As IWTable = section.AddTable()
    'Specifies the total number of rows and columns.
    table.ResetCells(2, 2)
    table(0, 0).AddParagraph().AppendText("Product Name")
    table(0, 1).AddParagraph().AppendText("Product Image")
    table(1, 0).AddParagraph().AppendText("Apple Juice")
    'Adds an image to the cell.
    Dim picture As IWPicture = table(1, 1).AddParagraph().AppendPicture(Image.FromFile("Image.png"))
    picture.Height = 75
    picture.Width = 60
    'Saves the Word document.
    document.Save("Sample.docx", FormatType.Docx)
End Using

Apply formatting to Table, Row and Cell

The following code example illustrates how to load an existing document and apply table formatting options such as Borders, LeftIndent, Paddings, IsAutoResized, etc.

NOTE

1. BorderStyle.None is the default value of BorderType property in Borders class which will not show borders for the table or cell. It is equivalent to border style not defined and borders can be inherited from style or parent formats.
2. To hide border for a table or cell in the Word Document, you can set BorderType property with BorderStyle.Cleared. It means border style defined as no border (Don’t show border) and shouldn’t inherit from style or parent formats.
3. To show/display border for a table or cell in the Word Document, you can set BorderType property with BorderStyle values (except BorderStyle.None and BorderStyle.Cleared).
4. As in the Microsoft Word, DocIO supports RowFormat.Borders in DOC format alone.

C# [Cross-platform]

//Creates an instance of WordDocument class (Empty Word Document)
FileStream fileStreamPath = new FileStream("Table.docx", FileMode.Open, FileAccess.Read, FileShare.ReadWrite);
//Opens an existing Word document into DocIO instance

Resize table

You can automatically resize the table cell to fit its contents based on the given autofit options such as FitToContent, FitToWindow, FixedColumnWidth.

The following code example shows how to resize the table in a Word document.

C# [Cross-platform]

//Loads an existing Word document into DocIO instance
FileStream fileStreamPath = new FileStream("Template.docx", FileMode.Open, FileAccess.Read, FileShare.ReadWrite);
WordDocument document = new WordDocument(fileStreamPath, FormatType.Docx);
//Accesses the instance of the first section in the Word document
WSection section = document.Sections[0];
//Accesses the instance of the first table in the section
WTable table = section.Tables[0] as WTable;
//Resizes the table to fit the contents respect to the contents
table.AutoFit(AutoFitType.FitToContent);
//Accesses the instance of the second table in the section
table = section.Tables[1] as WTable;
//Resizes the table to fit the contents respect to window/page width
table.AutoFit(AutoFitType.FitToWindow);
//Accesses the instance of the third table in the section
table = section.Tables[2] as WTable;
//Resizes the table to fit the contents respect to fixed column width
table.AutoFit(AutoFitType.FixedColumnWidth);
//Saves the Word document to MemoryStream
MemoryStream stream = new MemoryStream();
document.Save(stream, FormatType.Docx);
//Closes the document
document.Close();

C# [Windows-specific]

NOTE

In ASP.NET Core, UWP, and Xamarin platforms, to apply autofit for table in a Word document we recommend you to use Word to PDF assemblies or NuGet packages as a reference in your application.

Working with Table Style

A table style defines a set of table, row, cell and paragraph level formatting that can be applied to a table. WTableStyle instance represents table style in a Word document.

NOTE

Essential® DocIO currently provides support for table styles in DOCX and WordML formats alone. The visual appearance is also preserved in Word to PDF, Word to Image, and Word to HTML conversions.

The following code example illustrates how to apply the built-in table styles to the table.

C# [Cross-platform]

//Creates an instance of WordDocument class
FileStream fileStreamPath = new FileStream("Table.docx", FileMode.Open, FileAccess.Read, FileShare.ReadWrite);
WordDocument document = new WordDocument(fileStreamPath, FormatType.Docx);
WSection section = document.Sections[0];
WTable table = section.Tables[0] as WTable;
//Applies "LightShading" built-in style to table
table.ApplyStyle(BuiltinTableStyle.LightShading);
//Saves the Word document to MemoryStream
MemoryStream stream = new MemoryStream();
document.Save(stream, FormatType.Docx);
//Closes the document
document.Close();

C# [Windows-specific]

//Creates an instance of WordDocument class
WordDocument document = new WordDocument("Table.docx", FormatType.Docx);
WSection section = document.Sections[0];
WTable table = section.Tables[0] as WTable;
//Applies "LightShading" built-in style to table
table.ApplyStyle(BuiltinTableStyle.LightShading);
//Saves and closes the document instance
document.Save("TableStyle.docx", FormatType.Docx);
document.Close();

VB.NET [Windows-specific]

'Creates an instance of WordDocument class
Dim document As New WordDocument("Table.docx", FormatType.Docx)
Dim section As WSection = document.Sections(0)
Dim table As WTable = TryCast(section.Tables(0), WTable)
'Applies "LightShading" built-in style to table
table.ApplyStyle(BuiltinTableStyle.LightShading)
'Saves and closes the document instance
document.Save("TableStyle.docx", FormatType.Docx)

Apply Base Style

Table styles can be based on other table styles also. When applying a base style, the new style will inherit the values of the base style that are not explicitly redefined in the new style. You can apply a custom table style or a built-in table style as a base for the table style.

The following code example illustrates how to apply built-in and custom table styles as base styles for another custom table.

C# [Cross-platform]

//Create a new Word document.
using (WordDocument document = new WordDocument())
{
    //Add one section and paragraph to the document.
    document.EnsureMinimal();
    //Add a table to the Word document.
    WTable table = document.LastSection.AddTable() as WTable;
    table.ResetCells(3, 2);
    table[0, 0].AddParagraph().AppendText("Row 1 Cell 1");
    table[0, 1].AddParagraph().AppendText("Row 1 Cell 2");
    table[1, 0].AddParagraph().AppendText("Row 2 Cell 1");
    table[1, 1].AddParagraph().AppendText("Row 2 Cell 2");
    table[2, 0].AddParagraph().AppendText("Row 3 Cell 1");
    table[2, 1].AddParagraph().AppendText("Row 3 Cell2");
    //Add a new custom table style.
    WTableStyle tableStyle = document.AddTableStyle("CustomStyle1") as WTableStyle;
    tableStyle.TableProperties.RowStripe = 1;
    //Apply conditional formatting for the first row.
    ConditionalFormattingStyle firstRowStyle = tableStyle.ConditionalFormattingStyles.Add(ConditionalFormattingType.FirstRow);
    firstRowStyle.CharacterFormat.Bold = true;
    //Apply conditional formatting for the odd row.
    ConditionalFormattingStyle oddRowBandingStyle = tableStyle.ConditionalFormattingStyles.Add(ConditionalFormattingType.OddRowBanding);

Specifying table header row to repeat on each page

You can specify one or more rows in a table to be repeated as header row at the top of each page, when the table spans across multiple pages.

• In the case of a single header row, it must be the first row in the table.
• In the case of multiple header rows, then header rows must be consecutive from the first row of the table.

NOTE

Heading rows do not have any effect with nested tables in Microsoft Word as well as DocIO

The following code example illustrates how to create a table with a single header row.

C# [Cross-platform]

//Creates an instance of WordDocument class
WordDocument document = new WordDocument();
IWSection section = document.AddSection();
IWTable table = section.AddTable();
table.ResetCells(50, 1);
WTableRow row = table.Rows[0];
//Specifies the first row as a header row of the table
row.IsHeader = true;
row.Height = 20;
row.HeightType = TableRowHeightType.AtLeast;
row.Cells[0].AddParagraph().AppendText("Header Row");
for (int i = 1; i < 50; i++)
{
    row = table.Rows[i];
    row.Height = 20;
    row.HeightType = TableRowHeightType.AtLeast;
    row.Cells[0].AddParagraph().AppendText("Text in Row" + i.ToString());
}
//Saves the Word document to MemoryStream
MemoryStream stream = new MemoryStream();
document.Save(stream, FormatType.Docx);
//Closes the document
document.Close();

Keeping rows from breaking across pages

You can enable or disable the table row content to split across multiple pages, when the row contents do not fit in a previous page.

The following code example illustrates how to disable all the table rows from splitting across multiple pages.

C# [Cross-platform]

//Creates an instance of WordDocument class
FileStream fileStreamPath = new FileStream("Template.docx", FileMode.Open, FileAccess.Read, FileShare.ReadWrite);
WordDocument document = new WordDocument(fileStreamPath);
WSection section = document.Sections[0];
WTable table = section.Tables[0] as WTable;
//Disables breaking across pages for all rows in the table.
foreach (WTableRow row in table.Rows)
    row.RowFormat.IsBreakAcrossPages = false;
//Saves the Word document to MemoryStream
MemoryStream stream = new MemoryStream();
document.Save(stream, FormatType.Docx);
//Closes the document
document.Close();

C# [Windows-specific]

//Creates an instance of WordDocument class
WordDocument document = new WordDocument("Template.docx");
WSection section = document.Sections[0];
WTable table = section.Tables[0] as WTable;
//Disables breaking across pages for all rows in the table.
foreach (WTableRow row in table.Rows)
    row.RowFormat.IsBreakAcrossPages = false;
//Saves and closes the document instance
document.Save("Result.docx", FormatType.Docx);
document.Close();

VB.NET [Windows-specific]

'Creates an instance of WordDocument class
Dim document As New WordDocument("Template.docx")
Dim section As WSection = document.Sections(0)
Dim table As WTable = TryCast(section.Tables(0), WTable)
