Working with PowerPoint Tables

22 Mar 202424 minutes to read

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

NOTE

Adding more than 75 rows/columns not supported in the PowerPoint presentation using Microsoft PowerPoint application. It shows alert when you attempt to insert a table with more than 75 rows/columns, which is one of the behaviors of Microsoft PowerPoint and Essential Presentation does the same.

Create a table by adding rows

Essential PresentationĀ supports creating and editing tables in PowerPoint slides by adding rows. Refer to the following code example.

//Create a PowerPoint presentation
IPresentation pptxDoc = Presentation.Create();
//Add slide to the presentation
ISlide slide = pptxDoc.Slides.Add(SlideLayoutType.Blank);
//Add a table to the slide
ITable table = slide.Shapes.AddTable(2, 2, 100, 120, 300, 200);
//Initialize index values to add text to table cells
int rowIndex = 0, colIndex;
//Iterate row-wise cells and add text to it
foreach (IRow rows in table.Rows)
{
    colIndex = 0;
    foreach (ICell cell in rows.Cells)	
    {
        cell.TextBody.AddParagraph("(" + rowIndex.ToString() + " , " + colIndex.ToString() + ")");
        colIndex++;
    }
    rowIndex++;
}
//Save the PowerPoint Presentation as stream
FileStream outputStream = new FileStream("Sample.pptx", FileMode.Create);
pptxDoc.Save(outputStream);
//Close the presentation
pptxDoc.Close();
//Create a PowerPoint presentation
IPresentation pptxDoc = Presentation.Create();
//Add slide to the presentation
ISlide slide = pptxDoc.Slides.Add(SlideLayoutType.Blank);
//Add a table to the slide
ITable table = slide.Shapes.AddTable(2, 2, 100, 120, 300, 200);
//Initialize index values to add text to table cells
int rowIndex = 0, colIndex;
//Iterate row-wise cells and add text to it
foreach (IRow rows in table.Rows)
{
    colIndex = 0;
    foreach (ICell cell in rows.Cells)	
    {
        cell.TextBody.AddParagraph("(" + rowIndex.ToString() + " , " + colIndex.ToString() + ")");
        colIndex++;
    }
    rowIndex++;
}
//Save the presentation
pptxDoc.Save("Sample.pptx");
//Close the presentation
pptxDoc.Close();
'Create a PowerPoint presentation
Dim pptxDoc As IPresentation = Presentation.Create()
'Add slide to the presentation
Dim slide As ISlide = pptxDoc.Slides.Add(SlideLayoutType.Blank)
'Add a table to the slide
Dim table As ITable = slide.Shapes.AddTable(2, 2, 100, 120, 300, 200)
'Initialize index values to add text to table cells
Dim rowIndex As Integer = 0, colIndex As Integer
'Iterate row-wise cells and add text to it
For Each rows As IRow In table.Rows
    colIndex = 0
    For Each cell As ICell In rows.Cells
        cell.TextBody.AddParagraph("(" + rowIndex.ToString() + " , " + colIndex.ToString() + ")")
        colIndex += 1
    Next
    rowIndex += 1

Create a table by adding columns

The following code example demonstrates how to create a simple table in a PowerPoint slide by adding columns.

//Create a PowerPoint presentation
IPresentation pptxDoc = Presentation.Create();
//Add slide to the presentation
ISlide slide = pptxDoc.Slides.Add(SlideLayoutType.Blank);
//Add a table to the slide
ITable table = slide.Shapes.AddTable(2, 2, 100, 120, 300, 200);
//Initialize index values to add text to table cells
int row = 0, col;
//Iterate row-wise cells and add text to it
foreach (IColumn columns in table.Columns)
{
    col = 0;
    foreach (ICell cell in columns.Cells)
    {
        cell.TextBody.AddParagraph("(" + row.ToString() + " , " + col.ToString() + ")");
        col++;
    }
    row++;
}
//Save the PowerPoint Presentation as stream
FileStream outputStream = new FileStream("Sample.pptx", FileMode.Create);

Get the actual height of the table

The table height expands with the content added to it. The Essential Presentation library allows you to get this actual height or rendered height of the table. This property is a calculated value based on the content added to the table cells.

The following code example demonstrates how to get the actual height of a PowerPoint table.

//Loads or open an PowerPoint Presentation
FileStream inputStream = new FileStream("Sample.pptx", FileMode.Open);
IPresentation pptxDoc = Presentation.Open(inputStream);
//Initialize Presentation renderer
pptxDoc.PresentationRenderer = new PresentationRenderer();
//Get a table in the slide
ITable table = pptxDoc.Slides[0].Shapes[0] as ITable;
//Changing the paragraph content in the table
table.Rows[0].Cells[0].TextBody.AddParagraph("Hello World");
//Get the dynamic height of the table
float height=table.GetActualHeight();
//Save the PowerPoint Presentation as stream
FileStream outputStream = new FileStream("Table.pptx", FileMode.Create);
pptxDoc.Save(outputStream);
//Close the presentation
pptxDoc.Close();
//Opens existing PowerPoint file
IPresentation pptxDoc = Presentation.Open("Sample.pptx");
//Opens slide in the presentation
ISlide slide = pptxDoc.Slides[0];
//Open Table in the slide to make changes
ITable table = slide.Shapes[0] as ITable;
//Changing the paragraph content in the table
table.Rows[0].Cells[0].TextBody.AddParagraph("Hello World");
//Get the dynamic height of the table
float height=table.GetActualHeight();
//Save the presentation
pptxDoc.Save("Table.pptx");
//Close the presentation
pptxDoc.Close();
'Open an existing PowerPoint file
Dim pptxDoc As IPresentation = Presentation.Open("Sample.pptx")
'Get the table from the slide
Dim table As ITable = TryCast(pptxDoc.Slides(0).Shapes(0), ITable)
ā€˜Changing the paragraph content in the table
table.Rows[0].Cells[0].TextBody.AddParagraph("Hello World");
ā€˜Get the dynamic height of table
Dim height As float = table.GetActualHeight()
'Save the presentation
pptxDoc.Save("Table.pptx")
'Close the presentation
pptxDoc.Close()

NOTE

Getting the actual height of the table is not supported in UWP platform.

Applying table formatting

You can format a table to change its appearance by customizing the table border, cell background, cell margins etc. The following code example demonstrates how to apply the custom table formatting.

//Create an instance of PowerPoint Presentation
IPresentation pptxDoc = Presentation.Create();
//Adds slide to the Presentation
ISlide slide = pptxDoc.Slides.Add(SlideLayoutType.Blank);
//Adds table to the slide
ITable table = slide.Shapes.AddTable(2, 2, 100, 120, 300, 200);
//Retrieves each cell and fills text content to the cell.

ICell cell = table[0, 0];
//Sets the column width for a cell; this sets the width for entire column
cell.ColumnWidth = 400;

//Sets the margin for the cell.
cell.TextBody.MarginBottom = 0;
cell.TextBody.MarginLeft = 58;
cell.TextBody.MarginRight = 29;
cell.TextBody.MarginTop = 65;

//Sets the back color for the cell.
cell.Fill.SolidFill.Color = ColorObject.Orange;
cell.TextBody.AddParagraph("First Row and First Column");

cell = table[0, 1];
//Sets the margin for the cell.
cell.TextBody.MarginLeft = 58;
cell.TextBody.MarginRight = 29;
cell.TextBody.MarginTop = 65;

//Sets the back color for the cell.

Modifying the table

The following code example demonstrates how to modify the table in existing PowerPoint Presentation

//Loads or open an PowerPoint Presentation
FileStream inputStream = new FileStream("Sample.pptx", FileMode.Open);
IPresentation pptxDoc = Presentation.Open(inputStream);
//Gets slide from the Presentation
ISlide slide = pptxDoc.Slides[0];
//Gets table from slide
ITable table = slide.Shapes[0] as ITable;
//Modifies the table width
table.Width = 450;
//Changes the built in style of the table
table.BuiltInStyle = BuiltInTableStyle.DarkStyle1Accent2;
//Sets text content to the cell
table.Rows[0].Cells[0].TextBody.AddParagraph("Row1 Cell1");          
//Save the PowerPoint Presentation as stream
FileStream outputStream = new FileStream("TableModified.pptx", FileMode.Create);
pptxDoc.Save(outputStream);
//Close the presentation
pptxDoc.Close();
//Creates instance of PowerPoint Presentation
IPresentation pptxDoc = Presentation.Open("Table.pptx");
//Gets slide from the Presentation
ISlide slide = pptxDoc.Slides[0];
//Gets table from slide
ITable table = slide.Shapes[0] as ITable;
//Modifies the table width
table.Width = 450;
//Changes the built in style of the table
table.BuiltInStyle = BuiltInTableStyle.DarkStyle1Accent2;
//Sets text content to the cell
table.Rows[0].Cells[0].TextBody.AddParagraph("Row1 Cell1");
//Saves the Presentation
pptxDoc.Save("TableModified.pptx");
//Closes the Presentation

Merging the cells

The following code example shows how to merge cells in a table.

//Create an instance of PowerPoint Presentation.
IPresentation pptxDoc = Presentation.Create();
//Add slide to the Presentation.
ISlide slide = pptxDoc.Slides.Add(SlideLayoutType.Blank);
//Add table to the slide.
ITable table = slide.Shapes.AddTable(2, 2, 100, 120, 300, 200);

//Retrieve first cell.
ICell cell = table[0, 0];
//Retrieve each cell and fills text content to the cell.
cell.TextBody.AddParagraph("First Row and First Column");
cell = table[0, 1];
cell.TextBody.AddParagraph("First Row and Second Column");
cell = table[1, 0];
cell.TextBody.AddParagraph("Second Row and First Column");
cell = table[1, 1];
cell.TextBody.AddParagraph("Second Row and Second Column");

//Retrieve first cell.
cell = table[0, 0];
//Set the column span value to merge the cell.
cell.ColumnSpan = 2;

//Give simple description to table shape.
table.Description = "Table arrangement";
//Save the PowerPoint Presentation as stream.
FileStream outputStream = new FileStream(OutputFileName, FileMode.Create);
pptxDoc.Save(outputStream);
//Close the Presentation.
pptxDoc.Close();
//Create an instance of PowerPoint Presentation.
IPresentation pptxDoc = Presentation.Create();
//Add slide to the Presentation.
ISlide slide = pptxDoc.Slides.Add(SlideLayoutType.Blank);
//Add table to the slide.
ITable table = slide.Shapes.AddTable(2, 2, 100, 120, 300, 200);

//Retrieve first cell.

Removing the table

You can remove a table from a slide by its instance or by its index position in the shape collection. The following code example demonstrates removing a table in a slide.

//Loads or open an PowerPoint Presentation
FileStream inputStream = new FileStream("Sample.pptx", FileMode.Open);
IPresentation pptxDoc = Presentation.Open(inputStream);
//Gets slide from the Presentation
ISlide slide = pptxDoc.Slides[0];
//Gets the table from slide
ITable table = slide.Shapes[0] as ITable;
//Removes table from shape collection
slide.Shapes.Remove(table);        
//Save the PowerPoint Presentation as stream
FileStream outputStream = new FileStream("TableModified.pptx", FileMode.Create);
pptxDoc.Save(outputStream);
//Close the presentation
pptxDoc.Close();
//Creates instance of PowerPoint Presentation
IPresentation pptxDoc = Presentation.Open("Table.pptx");
//Gets slide from the Presentation
