I don't know what a "quadratic, same size" table is or what you mean. If you
do not get a satisfactory reply I suggest:
1. Read and follow the posting guide at the end of this message.
2. In particular, provide a simple, reproducible example to show what you
want to do and perhaps any error messages that you may have received.
