Click on the Table button on the Tables and Borders toolbar. A menu will appear.

Click on Delete Rows. The row in which the insertion point was positioned will be deleted.
If you want to create a row across the top of the table in which to make a heading, you can combine several cells into a single cell.
Click on the Eraser button. The mouse pointer will turn into an eraser.
Click on the cell border between the two cells that you want to merge. The border between the two cells will be deleted.
Click on the Eraser button again when you are finished merging cells.
You can also split a cell into several cells to make space for additional information.
