Splitting cells in Pages Table with additional lines
Hello, I've recently converted from Word to Pages. Using the pen tool Word allowed you to draw additional lines inside and across cells within a table. How can you do this in Pages? I have a 4 column table with 15 lines and I need to split columns 3 and 4 only into additional rows. I've found the line drawing tool and I've managed to draw one line but I can't get it to stay where I want it when I move onto the next line - and I can't keep the 'wrap' menu on view in the side panel to correct it every time it jumps back outside the table. Help please! Thanks.
