Remarks

Use this method to remove all HtmlTableCell objects from the HtmlTableCellCollection collection and reset the Count property to 0.

Бележка

This method removes the cells from a row, but it does not remove the row from the table. To remove a row from the table, be sure to also remove the HtmlTableRow object that represents the row from the Rows collection of the HtmlTable control.
