I am writing a two-column style article, using the A&A package. I'm trying to insert a single-column table, that is too large for one page, so I use the longtable package.
Because longtable has problems with the two-columns article, I have adopted this solution:
\onecolumn
\begin{longtable}{ccccccccccc}
*very long table*
\end{longtable}
And this solution works well, but on the last table page there is a long white space before the following paragraphs, and I don't want this:
Is there a way to cut that white space?
