This completely falls under the category of General Chess Discussion. Lol
Depends on your version, but you can probably highlight a column, and then right click -> add new column to add a column, and select a row, right click -> add new row to add a row.
There are other ways as well.
Does anyone know how when you have inserted a table into Microsoft Word, how you can add more columns/rows to the table if you used up the table and need more space?
Would be very appreciated if somebody could tell me...
