You can give the table a class: <table class="my-custom-table"...
Then apply specific CSS to it for padding, spacing etc..
However, if you’re wanting to add columns, use our Lightweight Grid Columns plugin: https://wordpress.org/plugins/lightweight-grid-columns/
Tables are meant for tabular data (stats etc..)
