I want to use longtabu in twocolumn paper in latex. My table has a lot fo rows and columns, so I want it to be full-width. I know longtabu does not support twocolumn and it throws error message when using it in twocolumn mode. I manually switched to one column mode by \onecolumn command and returned to twocolumn mode by \twocolumn. But it makes new page with lots of blank spaces before and after by using these commands. I want to do exactly what table* environment do. I mean without effecting other commands following longtabu. How can I do this? Any help would be appreciated.
