Hi
You need to set all of your head rows to "keep with next". Select Format -> Paragraph and then select the "Line and Page Breaks" tab and tick the "Keep with next" box. This will ensure that all heads stay with the text below it.
Then you need to take off the fixed row height you have set in your table. Any text entered in a cell will then expand that cell to fit its size as required.
If you need any further help then come back to me.
Good luck.
