Using plugin on blank page (Without template)

Hi guys,

I’ve basically created a sorted database using a plugin and is currently displaying in the main text part of my page. As shown here: https://pesmasterleague.com/home/mlb2/

Obviously this is nowhere near enough space for the table and was basically wondering how I could get this table on a blank page, or even just with the header, essentially removing the two sidebars for more width. The plugin being used for the table has to be used.

Any help would be much appreciated!

Thanks,
Paul
