Though the HTML table element is useful for long and tabular data, it is known for being problematic when used for layout. Some of the pending issues are not able to be solved with CSS only, because of weird table behavior, such as: #237 and #312. We should refactor and use CSS layout techniques such as flex row of columns.

addendum:

• - should refac app state to allow seamless claiming and permit switching
• - should show reward origin in case its fetched
• - claim all
• - improve on-chain reads
