How do I change the spacings between the scale points in a bipolar likert scale?

I have tried the below js:
jQuery(".Skin .Matrix .Bipolar tr.ChoiceRow td").css({"padding-right":"30px","padding-left":"30px"});


However, it’s resulting in mis-alignment between labels and scale points. In the image below you can see 1 and 6 shifting far out from the points below.

Can anyone please suggest a way out of this. Thanks in advance.
