Hi org-mode community,

The patch ensures the header of an org-table displays without the cursor
inside the table when org-table-header-line-mode is enabled.

BTW, this is my first patch for org-mode, so please correct me if there
are any issues with it.
Also, I've done the paperwork before.

Regards,
Zhe Lei

Thanks for the patch!
May you please explain in more details what problem you are trying to
solve?

Moving point to WS and then immediately to the beginning of the table
makes no difference. So, your patch does nothing.

Sure. I've identified an issue on the master branch where, if the cursor is
not inside the table at WS,  `org-table-begin' in
`org-table-header-set-header'
gets the beginning position of the next table in the buffer.
so `(pos-visible-in-window-p beg)' returns true, causing the header overlay
of the table at WS to not display.

> Moving point to WS and then immediately to the beginning of the table

Moving point to WS ensures`org-table-begin' to get the beginning position
of the table at WS, regardless of the cursor position, resolves the
above problem.

Thanks for the explanation. Now the patch makes more sense.
I am attaching a modified version of the patch with updated commit
message and a code comment added explaining why we need to move to WS.

P.S. Bastien, may your please check Lei Zhe's copyright status?

Applied, onto bugfix. I amended the commit author field to contain the
https://git.savannah.gnu.org/cgit/emacs/org-mode.git/commit/?id=5128460f9
full name.

Lei Zhe, you are now listed as an Org contributor. Thank you!
