The above was attached with Gnus 'C-c RET f', MIME type 'text/x-org'.
Reading with Gnus, I don't see any blank lines between the table info
and the table itself.

Just to get back to the original question:  Should and does
'tab:my_data' work as a value for a variable in a source block header?
I get

Reference 'my_data' not found in this buffer

If I replace the colon with '_', ';', or even '=', everything works as
expected.

Cheers,
