TableProperties.BackgroundColor Property

Specifies the table’s background color.

Namespace: DevExpress.Blazor.RichEdit

Assembly: DevExpress.Blazor.RichEdit.v24.1.dll

NuGet Package: DevExpress.Blazor.RichEdit

Declaration

public Color BackgroundColor { get; set; }

Property Value

Type	Description
Color	The table’s background color.

Remarks

The Rich Text Editor component allows you to specify a background color for the following table elements:

Table

The BackgroundColor property allows you to identify the table’s background color. Call the ChangePropertiesAsync method and specify the TableProperties.BackgroundColor setting to change the table’s background color.

Table Cell

The BackgroundColor property allows you to obtain the cell’s background color. Call the ChangePropertiesAsync method and specify the TableCellProperties.BackgroundColor setting to change the cell’s background color.

Note

A cell’s background overlaps the table’s background.

The following example applies different background colors to odd and even table rows:
