Can you send screenshot of page and kind of output you are getting
You can also use java scriptexecutor to scroll horizontally
Second screen shot is of my page screen.
I can scroll but what about half displayed name like Fst Nm.
For that i can increase the width of column but that is not proper solution.
and can't go every page and adjust the col width.
and if i do compare with xls value it says not matching but if adjust col width it says it matching.
