[Plugin: TinyMCE Advanced] Locking cell width in tables

Hi I really hope someone can help. I have spent hours trying to get my tables to appear the way I want them. I want each cell width to be ‘locked’ in width. ie. not based on how many characters I enter into it. I have set the table width, cell spacing and size of each cell but still find that each 3 in my column is not the same. They vary according to the text that is entered. I want them to be like a standard word table with text being pushed down if the cell is not wide enough to fit the contents.

Can anyone help please??

Thanks in advance.
