javascript - how to improve spacing using jquery plugin export to pdf -

I am importing multiple HTML tables using the jquery plugin using this line code

< Pre> & lt; Table = export ({type: 'pdf', separator: ',', escape: 'fottal', pdf fontsis: 8, pdf lift margin: 35}); & Gt; ; As a PDF & lt; / A & gt;

This data is showing, but the columns are similar to each other, how can I make a proper difference between the columns so that it is readable? Currently there is a lot of lessons that are not readable. One column merges with another
