Top-level column headers are missing in XLS exports

[AleksueiR]

Expected behaviour

For XLS exports, I expect the table to have two-level headers since the accessibility module adds top-level columns:
HTML table:

XLS:

Actual behaviour

The top-level headers are missing in the actual output.

Other

Same happens with CSV exports, but I don't think having two-level headers is a good idea for CSV files. They should probably keep the headers as they rendered without the accessibility module:

Hi,

Thank you for reporting.
This looks more like an enhancement suggestion than a bug, because both modules are not directly connected. The info is there, but given in a different format.

Not all info is there, when the accessibility module is added, the series names are stripped from the export:
