The spacing on a table seems to get messed up between two parts of a table. If you have one part which is constantly shown (a header) and parts which are revealed using JavaScript (and can also be hidden), when you trigger the JavaScript to hide and then show it, there seems to be a single pixel error. This builds up as you repeat the action. 

Reproducible: Always

Steps to Reproduce:
1. Load the attachment supplied. 
2. Click [Show] to reveal cells. 
3. Click [Hide] to hide.
4. Repeat as necessary, note the spacing after several actions. 
Actual Results:  
There was some kind of spacing when there shouldn't have been.

Expected Results:  
No spacing.
