Hi there
I specialize on working on live sites. It's an unavoidable situation where sometimes you have to work on a live site, and that is when I'm called upon.
I'm a WordPress expert (among other things). I will need some time to go through your existing setup, after which I can add the sidebar, extend the table and add the requisite table filters.
I'm available for work immediately.
PS, I hope the Sportspress plugin has the required hook to make modifications to the table. The page looks simple enough AND I know what I need to do, hence the price quote
