Related API Members

The following members return TableStyleElement objects:

• TableStyleElements.Item[TableStyleElementType]

Remarks

A table style consists of elements that are stored in the TableStyleElements collection. This object is returned by the TableStyle.TableStyleElements property. An individual table style element is a TableStyleElement object accessed from the collection by the corresponding member of the TableStyleElementType enumeration.

Each table style element specifies the format for a particular element of a table.

A TableStyleElement object provides a set of properties to customize format settings of the corresponding table element: TableStyleElement.Borders, TableStyleElement.Fill and TableStyleElement.Font.

If you want to create a table style providing a striped row or column format for a table, customize the FirstRowStripe, SecondRowStripe, FirstColumnStripe or SecondColumnStripe table style elements and set their TableStyleElement.StripeSize property, which specifies the banding rule.

To remove formatting from a table style element, use the TableStyleElement.Clear method.

Note

Built-in table styles and their elements cannot be modified.

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.
