The only way I know how to change columns names within a table is by doing it within the code (see this link )
set(t, 'ColumnName', {'MT', 'MSTd', 'VIP', 'LIP'});
which can't be done by the user directly using the GUI. Instead, you could create edit boxes above or on top of the uitable column headers where the user can edit them directly. Each of them could have a callback function that executes the set() command above so the ColumnName property is edited.
Another option would be to use the first row of the uitable as the header row and allow the columns to be editable by the user (which could result in other unintended consequences).
