[Interest] sizing QTableWidget columns

[Waitman Gobble]

I want QTableWidget columns to fit the data and also the far right 
column expand to use all available space.

{
     ui->vendorsGrid->clear();
     ui->vendorsGrid->setRowCount(0);
     
ui->vendorsGrid->setSelectionBehavior(QAbstractItemView::SelectRows);
     
ui->vendorsGrid->setSelectionMode(QAbstractItemView::SingleSelection);
     ui->vendorsGrid->verticalHeader()->hide();

     ui->vendorsGrid->setColumnCount(7);
     ui->vendorsGrid->setSortingEnabled(true);
     
ui->vendorsGrid->setHorizontalHeaderLabels(QString("idx;Active;Created;City;State;Country;Name").split(";"));

//load data

     ui->vendorsGrid->resizeColumnsToContents();
     
ui->vendorsGrid->horizontalHeader()->sectionResizeMode(QHeaderView::Stretch);
     ui->vendorsGrid->horizontalHeader()->setStretchLastSection(true);
     
ui->vendorsGrid->setSizePolicy(QSizePolicy::Expanding,QSizePolicy::Expanding);

}

This works on the first data load, but if I subsequently 'reload' the 
data, the right column does adjust to fit the data.  However it does not 
expand to use the available space, until I either click a column header 
ie 'sort', or resize the main window. Only then the right column expands 
to fill the available space. I've tried adding:

     this->resize(this->width(),this->height());

to force a resize but does not remedy the behavior.

I've tried changing the order of 
resizeColumnsToContents/sectionResizeMode/setSizePolicy to no avail.

I'm using Qt version 5.7.1 on FreeBSD 11.0-RELEASE-p9 #0

I appreciate help/suggestions.
