I'll convert your example to GFM.

  | first row, first column  | first row, second column  | first row, third column  |
  | ------------------------ | ------------------------- | ------------------------ |
  | second row, first column | second row, second column | second row, third column |

To me, this is more readable than the HTML version.

It's not fun to manually reformat those tables for readability. If I add something to the `second row, second column`, I have to add extra spaces to the `first row, second column`, or it will look janky.

  | first row, first column  | first row, second column  | first row, third column  |
  | ------------------------ | ------------------------- | ------------------------ |
  | second row, first column | exceptionally long second row, that makes second column look worse | second row, third column |
