[Qt-interest] QTableView::addColumn()

[Neel Basu]

Why there is no suchmethod like QTableView::addColumn() ?
in Model View architecture some data maynot come from model.
may be a check box or a edit button or a total, avg column that are calculated 
by the data from other columns.
all this columns are not a part of model so there should be an addColumn() 
method on view also so that data that are not coming from model would not 
have any relation with model

Do you all agree with me ?? or am I wrong ??
