Adding a New Table body
To create a new tbody:
  - To create a new table body above an existing table body, click at the
    beginning of the first cell in the first row of the table body and select
    the tbody entry in the Table
  sub-menu.
- To create a new table body below an existing table body, move the
    cursor to the end of the last cell in the last row of the table body and
    select the tbody entry in the Table
    sub-menu.
New table bodies can also be easily added to a table using the
Enter key. When a whole table body is selected (use
F2 on Windows and Esc on Linux for that), pressing
the Enter key create a new table body after the selected
table body.
