Remarks

Use this method to remove the HtmlTableCell object at the specified index from an HtmlTableCellCollection collection. The index number is zero-based; therefore, the first item in the collection has an index value of 0.

Note

If you specify an index that is outside the range of index values, an exception is raised.
