I want to remove all rows that contain ?
The issue is that ? could be in any of my 14 columns
I tried this code ("data" is the name of my table here)
data(ismember(data,'?'),:)=[];
but i get the error
Error using tabular/ismember (line 37)
A and B must both be tables, or both be timetables.

This works:
column1 = {'a'; 'b'; '?'; 'c'; 'd'}
column2 = {'a'; '?'; 'x'; 'c'; 'd'}
data = table(column1, column2)
% Now that we have sample data, delete any column with a '?' in it.
rowsToDelete = any(contains(data{:, :} , '?'), 2)
data(rowsToDelete, :) = []
