How to mix single and double columns in one document in latex?

Question

I have a document and you want to create it as a two-column document. This works fine with the twocolumn parameter in the documentclass command. But I have several tables and images that are too large and should be included using both columns. These tables and images should be mostly on the same page, so \ onecolumn and \ twocolumn are not an option (with some exceptions). I tried a multicol package, but, strangely enough, I lost my tables this way. So knows any other solution?

Answer 1

Yes, if you just need this for tables and numbers, use * -variant:

\begin{table*} \end{table*} \begin{figure*} \end{figure*} 

With them they will occupy both columns.
