jquery code causes unwanted space

[Itetrymor]

I am having an issue with an options and answers feature I have. If I select an options which contains an output of some many buttons e.g If I choose option 20, it will display 20 buttons, the problem I am getting is that at the bottom of the table column, the space drops down a little bit. It only does it when an option is changed and then the space remains throughout. My question is simply how can I stop the space at the bottom of the table column to increase when an option changes?I have found out that the code that is causing this problem is this:\[code\] //THE ISSUE IS HEREvar _x = $(e.currentTarget);var _y = _x.closest('td.extratd');var _z = _y.prev();$('textarea', _z).css('height', '').height(_z.innerHeight());//ISSUE ABOVE\[/code\]Now what the code above does is allow the textarea within the \[code\]Question\[/code\] column to fill the whole table cell when ever the textarea is appended or if the option changes. So I need the code above but what the code above also does is create an unnecessary space at the bottom of the table row so I need help to sort out the unwanted space.I have a jsfiddle here which you can use to see what is happening and it also includes the code above: http://jsfiddle.net/aND4g/61/Please follow steps below in order to use fiddle:[*]When you open fiddle, on top type in a content in the question textarea and then click on \[code\]Open Grid\[/code\] and select button \[code\]3\[/code\] or \[code\]4\[/code\].[*]When you have done step 1 then click on the \[code\]Add Question\[/code\] button to append the above details into the table below[*]Now WITHIN THE APPENDED ROW, click on the \[code\]Open Grid\[/code\] and select the other option from what you first chosen. You will see that it creates an unwanted space at the bottom of the table row
