gra.table.resize
Set the number of rows and columns for a table. This action does not resize the control, simply the number of cells contained within the virtual table.
The action arguments are:
control
The name of the table control to resize.
rows
The number of rows for the table. Specifying 0 will leave the current
number of rows unchanged.
columns
The number of columns for the table. Specifying 0 will leave the current
number of columns unchanged.
When the table is resized, a gre.table.resize event will be emitted.
