Border not rendering in I.E / Edge

I’m just finishing off building a new website and when testing in Microsoft browsers the borders are not rendering in the table except for the right hand side. The borders show perfectly in other browsers.

I’ve tried various fixes that i’ve found on the web but nothing seems to work for me.

If anyone could help me i would be eternally grateful.

Thank you
