Hi @TomMartens ,
Thank you for looking into my question.
It it not about table headers per se (I misused the 'header' term because the date is placed in the header of the source document). The context here is gathering data from a folder with multiple similar reports, and therefore I need this time-stamp to separate each report in my joint table.
In other words: I would like to add a column to the data table with this date.
Sorry for poor explaining...
