Pushbuttons for Self-Defined Functions

Arrange the above-mentioned functions as pushbuttons with no fixed position. Place them horizontally and left-aligned below the table control in the order:

Insert line(s)
Delete line(s)
other functions

Use the appropriate icons for these functions.

Alternatively, you may arrange these functions to the right of the table control, starting at the lower border of the table.

Do not position the general clipboard functions Cut, Copy, and Paste as pushbuttons at the table control. They are not limited to the table control, but effect all selected screen objects. Therefore, position them in the standard toolbar.
