Lyx: Two column document - problem with table and table caption positioning

Question

I have a two-column document in Lyx with a table. First obstacle I had is that table respected the two-column rule, so it tried to fit it in one column only and ended up overflowing. I tried to fix this by using "span columns" option which was recommended, but after doing so, the table just disappeared.

In the end I solved this by adding \usepackage{cuted} to the preamble and placing the table inside \begin{strip} \end{strip} commands. My problem now is that table caption still respects two-column rule, so it wraps after it reaches end of one column.

Is there any way I can force it to wrap after it reaches end of the table?

Here is a MWE generated by Lyx:

(Some unnecessary text to allow me to save the answer.)

Answer 2

In general the table* environment is used to put a table at the top of a two-column page, with the table and caption covering both columns. Do not use the [H] specification with this. Here is a revised version of your MWE (I couldn't be bothered to eliminate all the code that had nothing to do with your problem).
