Here is the test case for the bug. If an empty tbody is specified then the link in the tfooter is inaccesible except for the left pixel, or however wide the first TH in the theader is.

Tested platforms Tested under mozilla 1.4 (linux), 1.5b(linux), 1.4(windows), Firebird 0.6 (windows and linux). Extra note.. HTML 4.01 spec does require that the tbody NOT be empty however. So, the workaround for me is to rework my templates.

Bug 173277 probably explains why the link is not clickable, but the primary concern here is that the colspan attribute does not work for <tfoot> when there is an empty <tbody></tbody> group in a 'border-collapse: collapse' table.
the problem has nothing to do with tfoot, just a empty row group is enough
changing title
the patch addresses only the cellmap problem, the drawing of the collapsed borders is still wrong

I fixed the cellmap issue, the border drawing is still not correct.

Empty rowgroups are illegal HTML 4.01, I don't think we should care for them too much. At most, it will be an enhancement, not a bug...

I had mentioned that the spec for HTML5 allows for empty TBODY elements on another bug report that has been marked duplicate of this one. I didn't want that change to go unacknowledged in this main bug report This should not be considered an enhancement request but a full fledged bug: http://www.w3.org/TR/html5/the-tbody-element.html#the-tbody-element

FWIW people still hitting this bug (and being surprised about how long-lived it is) https://github.com/twbs/bootstrap/issues/27949

I just ran into this bug. Really suprised that it exists for 16 years now. Currently, I use this work-around: https://stackoverflow.com/questions/33168178/why-does-firefox-not-render-border-of-table-with-empty-tbody

I just ran into this bug as well. It cost me several hours to discover the cause.

This bug is still present in Firefox 91 (august 2021), even though HTML 5 allows empty tbody. The problem does not happen on Chromium. I've passed about 5 hours figuring the cause, so I believe It would be nice to solve it. Here is my sample code:
<!doctype html>
<html>
<head>
<meta charset = 'utf-8'>
<style type = "text/css">
table{
border: 1px solid black;
border-collapse:collapse;
}
table td{
border: 1px solid black;
}
</style>
</head>
<body>
<table>
<tbody>
<tr><td>1</td><td>2</td></tr>
<tr><td>3</td><td>4</td></tr>
</tbody>
<tbody>
</tbody>
<tbody>
<tr><td>5</td><td>6</td></tr>
</tbody>
</table>
<table>
<tbody>
<tr><td>1</td><td>2</td></tr>
<tr><td>3</td><td>4</td></tr>
</tbody>
<tbody>
<tr><td>5</td><td>6</td></tr>
</tbody>
</table>
</body>
</html>

The severity field for this bug is relatively low, S3. However, the bug has 9 duplicates.
:dholbert, could you consider increasing the bug severity?

The last needinfo from me was triggered in error by recent activity on the bug. I'm clearing the needinfo since this is a very old bug and I don't know if it's still relevant.

Yes it's still relevant. I'm using v106.0.1 and sadly, after 20 years this bug still exists. Workaround also still works around... tbody:empty{display:none;}

I've also had it for many years. Now I'm using v122.0.1. When I decided to take a closer look at it in my projects, I found out using search queries that it is caused by using the style
table { border-collapse: collapse; }
In my case
tbody:empty{display:none;}
does not help. I'm using
@-moz-document url-prefix() { table.table-bordered > tbody:after {
content:''
} }
