I have been working with a very long table with some 200 rows with multiple rows of text in each row. The need for the table has been very well satisfied by Confluence, and really happy with the information we have been able to store in the table.

When viewing the table, the frozen header row is extremely helpful for scrolling down. It would be handy to be able to select more than one row as "header" rows, but that is another issue.

However, when editing the table, it is a pain not to have the header row visible, to confirm what each column is for.

My suggestion is that, if possible around still being able to edit the header row, that when scrolling down in a table in edit mode, that the header row is also frozen to make the editing of the various columns of data significantly easier.
