Class SFTable

Implements a two-dimensional table that holds an SFArrayList of rows. Each row is an SFArrayList of objects.

Inheritance

System.Object

SFTable

Implements

ICloneable

Namespace: Syncfusion.XlsIO.Implementation.Collections

Assembly: Syncfusion.XlsIO.Portable.dll

Syntax

public class SFTable : Object, ICloneable

Remarks

This is a memory efficient way to represent a table where values can remain empty. Only rows that actually contain data will allocate an SFArrayList and the array only holds as many objects as the specific row contains columns.

When you access data that are out of range, an empty () object will be returned. If you set data that are out of range, an exception will be thrown. If you set data for a row that is empty, the row will be allocated before the value is stored.

SFTable provides methods that let you insert, remove or rearrange columns or m_arrRows in the table.

Constructors

SFTable(SFTable, Boolean)

Initializes a new instance of the SFTable class and optional copies of data from an existing table.

Declaration

protected SFTable(SFTable data, bool clone)

Parameters

Type	Name	Description
SFTable	data	Table to copy.
System.Boolean	clone	Indicates whether to copy data.

SFTable(SFTable, Boolean, Object)

Initializes a new instance of the SFTable class and optional copies of data from an existing table.

Declaration

protected SFTable(SFTable data, bool clone, object parent)

Parameters

Type	Name	Description
SFTable	data	Table to copy.
System.Boolean	clone	Indicates whether to copy data.
System.Object	parent	Parent object for the new items.

SFTable(Int32, Int32)

Initializes a new instance of the SFTable class that is empty.

Declaration

public SFTable(int iRowCount, int iColumnCount)

Parameters

Type	Name	Description
System.Int32	iRowCount	Number of rows in the collection.
System.Int32	iColumnCount	Number of columns in the collection.

Properties

CellCount

Returns number of cells in the collection. Read-only.

Declaration

public int CellCount { get; }

Property Value

Type	Description
System.Int32

ColCount

Gets the number of columns contained in the SFTable. Read-only.

Declaration

public int ColCount { get; }

Property Value

Type	Description
System.Int32

Item[Int32, Int32]

Gets / sets an element at the specified coordinates in the SFTable.

Declaration

public object this[int rowIndex, int colIndex] { get; set; }

Parameters

Type	Name	Description
System.Int32	rowIndex	The zero-based row index.
System.Int32	colIndex	The zero-based column index.

Property Value

Type	Description
System.Object

Remarks

If you query for an element and the coordinates are out of range, an empty (null) object will be returned.

If you set an element and the the coordinates are out of range, an exception is thrown.

RowCount

Gets the number of rows contained in the SFTable. Read-only.

Declaration

public int RowCount { get; }

Property Value

Type	Description
System.Int32

Rows

Returns the SFArrayList from all rows.

Declaration

public SFArrayList<object> Rows { get; }

Property Value

Type	Description
SFArrayList<System.Object>

Methods

Removes all elements from the SFTable.

Declaration

public void Clear()

Clone()

Creates a deep copy of the SFTable.

Declaration

public virtual object Clone()

Returns

Type	Description
System.Object	A deep copy of the SFTable.

Clone(Object)

Creates a deep copy of the SFTable.

Declaration

public virtual object Clone(object parent)

Parameters

Type	Name	Description
System.Object	parent	Parent object for the items.

Returns

Type	Description
System.Object	A deep copy of the SFTable.

Contains(Int32, Int32)

Indicates whether an element is at the specified coordinates in the SFTable.

Declaration

public bool Contains(int rowIndex, int colIndex)

Parameters

Type	Name	Description
System.Int32	rowIndex	The zero-based row index.
System.Int32	colIndex	The zero-based column index.

Returns

Type	Description
System.Boolean	true if an element exists at the specified coordinates in the SFTable; false otherwise.

CreateCellCollection()

Creates a collection of cells for a row.

Declaration

public virtual SFArrayList<object> CreateCellCollection()

Returns

Type	Description
SFArrayList<System.Object>	An SFArrayList or derived object for the cell collection.
