how to add a column to a tall table?

Hi,

I want to add a column of "1" to a tall table, but getting this error : "Indexed assignments of the form T(...,...) = B are not supported for tall table."

This is the first time i'm using tall arrays, tried applaying the tall indexing help but with no sucsess...

this is my code:

Ge_table(Ge_table.energy < 0, :) = []; %remove bad events in HPGe

Ge_table.ColumnNew = tall('detector'); % this was a try to create a new column

Ge_table.detector = {1};

Ge_table.Properties.VariableNames{4} = 'detector'; %this is another try as the in-memory method
