How can you wrap the word longWord_anotherLongWord_long_again to many lines in the tabular environment?
The word should be
LongWord_
anotherLongWord_
long_again
\bgroup \catcode`\_=13% \def_{\textunderscore\hskip0pt}% \begin{tabular}{|l|l|p{4.5cm}} test_444 & 555 & longWord_anotherLongWord_long_again_too_long_very_long_ha_ha_ha_ha\\\hline \end{tabular} \egroup
Be careful though; this will produce the desired result, but TeX will complain about underfull boxes.
