Column LABELS in reports

[arturkulik]

Hi, i've met situations that we need to send reports to external users and colmuns names ale not fiendly at all - technical data sometimes long phrases

It would be nice to have additional field in report panel to rename column's names for report files as:

[yuri]

It was planned. Was requested before. IIRC, there was some blocker or it was more complicated than appeared.
