void QTableWidget::setRowCount(int rows)

I might only need 100 rows. Or I might need 200000 rows.
How should I set rows? I should set more than 200000?

Hi
set setRowCount to what you would expect.
You can always raise or lower it.
So really not that important from start.
When you add a row, you can raise it.
