Re: [csswg-drafts] [css2][css-tables] Do collapsed tracks also shrink the table wrapper box or only the table grid box? (#11408) from Oriol Brufau via GitHub on 2025-01-08 (public-css-archive@w3.org from January 2025)

I tried to align Servo with Gecko, but there are various tests that check that collapsed columns shrink the `offsetWidth` of the table. Seems like Gecko is doing something special:

```html
<!DOCTYPE html>
foo
<table style="display: inline-table; width: 100px; height: 50px; border: 5px solid; outline: 5px solid magenta; box-sizing: content-box">
  <col style="visibility: collapse"></col><col></col>
</table>
bar
<pre></pre>
<script>
var t = document.querySelector("table");
document.querySelector("pre").textContent = `
  clientWidth: ${t.clientWidth}
  offsetWidth: ${t.offsetWidth}
  getBoundingClientRect().width: ${t.getBoundingClientRect().width}
  getClientRects()[0].width: ${t.getClientRects()[0].width}
`;
</script>
```
