Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.

Remarks

The TableCell class represents a cell in a Table control. You can use the Text property to specify or determine the contents of the cell.

This class allows you to control how the contents of the cell are displayed. The alignment of the contents in the cell are specified by setting the HorizontalAlign and VerticalAlign properties. You can use the Wrap property to specify whether the contents of the cell wrap in the cell.

You can also specify how many rows or columns in the table, represented by a Table control, are occupied by an individual cell. The RowSpan and ColumnSpan properties control how may rows and columns are used, respectively.

CAUTION   This control can be used to display user input, which might include malicious client script. Check any information that is sent from a client for executable script, SQL statements, or other code before displaying it in your application. ASP.NET provides an input request validation feature to block script and HTML in user input. Validation server controls are also provided to assess user input. For more information, see Validation Server Controls.
