Adjust width and padding of data tables

I have around 6 tables those padding or width is different.When I was not using data tables, their padding and width were set inline. Now the inline doesn't work.

I simply need to be able to add some padding and width Inline to data-tables or may be I could give those tables a class name and then give them padding and width.

I have also asked on stackoverflow please check here
