[GitHub] [incubator-superset] kgabryje opened a new pull request #12257: perf: Optimize performance of Results and Samples tables on Explore [WIP]

kgabryje opened a new pull request #12257:
URL: https://github.com/apache/incubator-superset/pull/12257


   ### SUMMARY
   This PR fixes an issue described in a comment https://github.com/apache/incubator-superset/issues/11968#issuecomment-747945240
   I wrapped table components in React.memo and removed unnecessary rerenders of copy to clipboard button.
   However, the biggest change is adding virtualization (react-window) for react-table, which improves the performance drastically for tables with many rows.
   However, due to how react-window works (which is wrapping row components in 2 divs) I had to stop using `<table>` and other table-related html tags in favour of divs, since the divs from `react-window` were breaking the table. Also, I needed to add a react-table plugin `useBlockLayout`, which requires the table cells to have fixed widths. The result is that we no longer benefit from cell widths being calculated by the browser, which is a huge bummer. I tried a few hacks to keep `<table>` tags (like wrapping divs generated by react-table in `<td>`), but all of them generated layout issues.
   I'd appreciate any suggestions on how I could improve this PR, especially when it comes to solving the issues with table layout!
