#Remarks

A Table consists of cells combined into rows. The Rows property stores all table rows. A row stores its cells in the Cells property. Call the InsertAsync/RemoveAsync method to add/remove a cell to/from the row. Perform this action for each table row to add or remove a table column.

The following example removes an existing column and adds two new columns to a table:
