The video below shows the process of how to split cells in a table (click the button on the bottom right of the video to expand the view). You can also follow the screen shots and steps below this.
2) Click on the 'Pages' button in the left hand side of the Toolkit.
3) Select the page you wish to edit
4) Click Show Tables in the wizard
5) A pop up box will appear to inform you that any changes you have made to the page will be saved before you move into Edit Table mode. If you do not see a pop-up window, please make sure you have added 'https://www.thetoolkit.co.uk' as a safe site on any pop up blocking software you are running.
6) The Table toolbar will appear in the wizard
7) Similarly to merging cells, you can split the cells down, or right, effectively allowing you to undo what you had done by merging the cells. Click on your table inside the cell you wish to split, and press either the split cells down or split cells right button (depending on whether you want a cell to be split in half horizontally or vertically).
8) When you have clicked the split cells button your cells will automatically split. If nothing happens, it is probably because you have clicked inside a cell which has not previously been merged.
