Gets a table style element by its type.

Namespace: DevExpress.Spreadsheet

Assembly: DevExpress.Spreadsheet.v19.1.Core.dll

Declaration

C#

TableStyleElement this[TableStyleElementType index] { get; }

VB.NET

ReadOnly Property Item(index As TableStyleElementType) As TableStyleElement

Parameters

Name	Type	Description
index	TableStyleElementType	A TableStyleElementType enumeration member.

Property Value

Type	Description
TableStyleElement	A TableStyleElement object that is a table style element of the specified type.

Remarks

A table style (TableStyle) consists of the collection of table style elements (TableStyle.TableStyleElements). Each table style element (TableStyleElement) specifies formatting for a particular element of a table. Use the Item property to access and modify individual table style elements.

A TableStyleElement object provides properties to customize the borders (TableStyleElement.Borders), fill (TableStyleElement.Fill) and font (TableStyleElement.Font) for the corresponding table element. If you want to create a style providing striped row or column formating for a table, customize the FirstRowStripe, SecondRowStripe, FirstColumnStripe or SecondColumnStripe table style elements and set their TableStyleElement.StripeSize property, which specifies the banding rule.

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.
