Edit Tables

Hello. Could you help us with the function of merging cells and changing the rows' or columns' position? It's very important to us. Most of the time, we couldn't plan the outline of a table appropriately, so we need to change the rows' position, but now we can only input it again. It wastes a lot of time. Could you help us solve it as soon as possible? Hope Outline will be getting better. Thank you very much!
