calc how do I enter text above a table

I want to put lines of text spreading across the width of the table - spanning several columns - but wrapping.
If I wrap it now it is all concentrating on one cell. How can get it to spread over the whole table and wraps at the end of the page ?

I cannot understand at all the text of the question. In specifict I don’ see it in any relation to the subject.
My answer only regards the subject therefore.

Hi

if the tag is correct, wouldn’t the answer be more like cell merging (with all its problems)?

Regards

Thanks! You are right. I didn’t check the tags at all. This on me!
Concerning the “merging” of cells the help should tell enough.
It should. But it still mentions “merging into a single cell” despite the fact that only the areas are merged, and the cells made invisible this way still exist.
Anyway I will delete my improper answer.
