TableProperties.CellMargins Property

Specifies margin settings for all cells in the table.

Namespace: DevExpress.Blazor.RichEdit

Assembly: DevExpress.Blazor.RichEdit.v24.2.dll

NuGet Package: DevExpress.Blazor.RichEdit

Declaration

public Margins CellMargins { get; set; }

Property Value

Type	Description
Margins	An object that contains margin settings.

Remarks

The Rich Text Editor component allows you to specify margin settings for the following table elements:

Table

The CellMargins property allows you to obtain margin settings common to all cells. Call the ChangePropertiesAsync method and specify the TableProperties.CellMargins setting to customize margins of all cells simultaneously.

Table Cell

A cell stores its margin settings in the Margins property. Call the ChangePropertiesAsync method and specify the TableCellProperties.BackgroundColor setting to customize cell margins.

Note

A cell’s Margins property takes priority over the table’s CellMargins property.

The following example configures cell margins:
