How do I (neat idea from spreadsheet) set up to have multiple levels of columns

[dabeegmon]

So - - - in Calc (libreoffice) it is possible to set up so that there are hidden columns.
So I could show 30 columns and have a group of 4 columns hidden between columns 4 and 5 (on the initial view) and another save 7 columns between columns 16 and 17 (on the initial view).
In my project I would like to find some way to have some total of perhaps 55 (maybe a few more) columns but that there are only perhaps 25 showing initially. Then there would be some kind of a marker (maybe some kind of a button) and then say 15 more columns appear. Next would be perhaps another 5 columns that are within the third level of columns and another 8 columns on level 2.

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 31 32 33 34 35 44 45 46 47 48
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx16 17 18 19 20 21 22 23 24 25 36 37 38 39 40 41 42 43
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx 26 27 28 29 30

(hopefully the above graphic (blech - - - not that good) but maybe it helps)
(used x's to fill space so there would be at least a hint at alignment)

Is this possible?

If so - - - maybe a pointer toward the process? (I'm prepared to do more than some work but I have no idea on even how to start!)

TIA

There is a hide function on the column. If you are trying to hide certain columns before the table is displayed, you can do something like the following... iterate over the columns, find the ones you want, then call the hide method.

dt = Tableview(master=app, coldata=col_data, rowdata=row_data)
dt.pack(fill='both', expand=1, padx=5, pady=5)

hidden_columns = ['Employee', 'SerialNumber']  # can also use `cid`, the index, or another identifier

for col in dt.tablecolumns:
    if col.headertext in hidden_columns:
        col.hide()

Thank you ever so much - - - that will definitely make things easier.

Is the function nestable?
(ie more than one level of hideability)
