Tow dimensional data table from tree branches?

Hi all,
i wrote a script with the use of xls read and write modul to handle excel data.
To show all branches (column from the xls file) i get a loooooong list with different branches in a vertical panel.
Is it possible to switch the panel from vertical to horizontal view ?
At the moment i tried pretty table python modul but maybe there is another option to show the data in a 2d grid.

This would be the goal

instead of this
