I think that does work in some browsers but not in others. And I'm not
sure about it.
The spec (CSS 2.1 17.5.2.2) says:
Calculate the minimum content width (MCW) of each cell: the
formatted content may span any number of lines but may not overflow
the cell box. If the specified 'width' (W) of the cell is greater
than MCW, W is the minimum cell width ...
So what does "may not overflow the cell box" mean?
If overflow is set to hidden, in the technical CSS sense, the box still
overflows. The overflow property just says what to do about, not that it
hasn't happened.
But if the overflowing bit has been clipped, because overflow was set to
hidden, then you might say in ordinary language that the box no longer
overflows.
On the former interpretation, which I favour, the value of the overflow
property should make absolutely no difference to minimum content width.
So it shouldn't stop table-cells growing past their set widths to fit
long unbreakable sequences.
The same thing applied to shrink-to-fit calculations for floats was
behind the anomaly observed by dorayme on htmldog.com recently. Firefox
allowed a big <pre> element to be shorter than its minimum content width
because it had overflow: scroll.

Yes, it sounds like the best thing would be one big table. That will
make sure the headings line up with the columns properly.
