Yes, thanks, it works fine for me.

No need for deep testing :-) Any table without a width option fails.

\bTR \bTD A \eTD \bTD x \eTD \bTD B \eTD \eTR

\v!fit ->f
\doifdimensionelse ...mensionelse \scratchdimen #1
<argument> ...pan \doifdimensionelse \tbltblwidth
                                                   \donefalse \donetrue  

\secondoftwoarguments #1#2->#2

\handleTBLcell ... \donetrue \else \donetrue \fi }
                                                   \ifdone \ifnum 0\number  
l.22 \eTABLE

What is the expected benefit of the patch in comparison with switching off  
the squeeze stuff, since I haven't seen yet a side effect of using  
\squeezeTBLspanfalse ?
