Steps to reproduce the problem:
1. Open attached URL
2. See Bad and Good examples

What is the expected behavior?
The first column in the Bad example should have zero width.

What went wrong?

It works as expected in Edge and FireFox

I am able to reproduce this bug in Safari 15.6.1 and STP 151 as can be seen from attached screenshot using JSFiddle from Comment 0. Both Chrome Canary and Firefox Nightly match each other as can be seen from attached screenshot. Thanks!

A workaround for this bug is to use a very small width that is greater than zero, e.g. "0.0001px", for the column that should have a zero-width.

This being a solution indicates that zero-width columns are somehow not considered by the layout algorithm.
