Is column sub sorting possible in QSortFilterProxyModel?

Pada_

Can one of the five QSortFilterProxyModel columns be sort and the other columns not sort?

What "five columns"?
In the normal course, QSortFilterProxyModel can sort by one chosen column, so is that not exactly what you want?

QSortFilterProxyModel

The number of columns is five. You are currently using QSortFilterProxyModel. I want to use the last two columns as a normal model that can not be sorted.

Sorry, I still don't really understand what you are asking.
You can only use one column at a time to sort by in a QSortFilterProxyModel (if you want to sort by multiple columns at a time, please say so).
If you want to disallow sorting by some of the columns, you could sub-class to implement that, e.g. override QSortFilterProxyModel::sort(int column) and do nothing for certain values of column.

Just to clarify, do you want:

Number	Letter
4	a
2	b
1	c
3	d

to be sorted like this (i.e. the second column doesn't change)

Number	Letter
1	a
2	b
3	c
4	d

Or do you just want people to be unable to sort by Letter and only sort by Number?

The table below (this sort is the same as the second column does not change). How can I do that?
