TableStyleCollection.Add(String) Method

Creates a new table or pivot table style with the specified name and appends it to the collection of styles.

Namespace: DevExpress.Spreadsheet

Assembly: DevExpress.Spreadsheet.v18.2.Core.dll

Declaration

C#

TableStyle Add(
    string name
)

VB.NET

Function Add(
    name As String
) As TableStyle

Parameters

Name	Type	Description
name	String	A String value that specifies the style name. Initializes the TableStyle.Name property of the created style.

Returns

Type	Description
TableStyle	A TableStyle object that specifies the newly created style.

Remarks

Call the Add method to create a custom table or pivot table style. Set the TableStyle.IsTableStyle and TableStyle.IsPivotStyle properties to the appropriate values, depending on whether the created style should be used for a table or pivot table. To ensure that the collection does not already contain a style under the specified name, use the TableStyleCollection.Contains method.

To create a new table or pivot table style that copies all the format settings of an existing style, use the TableStyle.Duplicate method.

Example

This example demonstrates how to create a custom style to format tables.

1. Add a new table style to the IWorkbook.TableStyles collection by calling the TableStyleCollection.Add method with the table style name passed as a parameter. This method returns the TableStyle object that represents the newly created table style. This object’s TableStyle.Name property is set to the specified name. Other settings are identical to the None table style (the default built-in table style that specifies no formatting for a table).

   Note

   Note that table styles have unique names in the collection. To ensure that there is no table style under the specified name in the collection, use the TableStyleCollection.Contains method.

2. Modify elements of the created table style (TableStyle.TableStyleElements) within the TableStyle.BeginUpdate and TableStyle.EndUpdate paired methods.
