Unable to create a fixed header in a table

[Love ac]

I have tried a table on a new page with no other elements. I cannot get the header to stay fixed.

Hi @Love ac,

Please, check this list:

• Table has no header row or there are cells in the top row that aren't marked as headers.
• Table has a header column, instead of a header row, and scrolls horizontally.
• Table сontains another table, that has its own header row.
