Adam,
Using the mouse to adjust the cell size in a table is way too difficult. Just trying to get a cell selected is a very difficult task. The mouse has to be so exactly positioned and even then its not consistent. Also, there is only one multi-direction cursor presented, so the user can't just set the width or just set the height...
Can you please use standard sizing tools so that we can adjust the width using the typical width drag (<-->) and height cursors, and make them not so sensitive (I think the standard range is +/- 5 pixels).
Tables are the only way in CE that users can format rows, so they are very, very important in document editing and currently the whole method of setting their widths and heights is just too non-intuitive and difficult.
Thanks
