Actions column `width: 0%` is causing wrong initial column width when any column is resizable

[artvinn]

Describe the bug
Constraining actions column width with width: 0% is messing up initial column size when any other column is set to resizable.

In the docs example Constraining the actions column width it's suggested to set width: 0% on actions column. However, when any other column is set to resizable: true, initial width is wrong for actions column, and column title is not shown.

To Reproduce
Example: codesandbox

Compare the results by switching "name" column resizable property to false.

Expected behavior
I expect the table to be rendered exactly the same when column is resizable.

The issue first appeared with this PR #711 and I narrowed it down to the addition of table-layout: fixed. If I set it to auto the problem goes away, but from the code I understand that this change is important. And I don't understand why it's necessary to set the table to fixed layout. @gfazioli maybe you have any ideas how to go about this issue?
