Resizing TableRow with nested table

  • I have a problem with tables and i need help.

    I´m creating a table into cell of other table (NESTED TABLE). and i whould like that this nested table expand itself when changing the row heigth of master table. Sample:

    Start Table moment:

    Code
    +--------------------+--------------------+--------------------+|  aaaaaaa           |+------------------+|                    ||                    ||  NESTED TABLE    ||                    ||                    |+------------------+|                    |+--------------------+--------------------+--------------------+

    When user type more text on cell(0,0), or he expand the rowheight with mouse, then nested table show me this way:

    Code
    +--------------------+--------------------+--------------------+|  aaaaaaa           |+------------------+|                    ||  bbbbb             ||  NESTED TABLE    ||                    ||  bbbbb             |+------------------+|                    ||  bbbbb             |                    |                    ||  bbbbb             |                    |                    ||  bbbbb             |                    |                    |+--------------------+--------------------+--------------------+

    but i would like that wptools automaticaly expand the nested table too. this way

    Code
    +--------------------+--------------------+--------------------+
    |  aaaaaaa           |+------------------+|                    |
    |  bbbbb             ||  NESTED TABLE    ||                    |
    |  bbbbb             ||                  ||                    |
    |  bbbbb             ||                  ||                    |
    |  bbbbb             ||                  ||                    |
    |  bbbbb             |+------------------+|                    |
    +--------------------+--------------------+--------------------+
