Look this post : http://forum.qt.io/topic/1715/qtablewidget-how-to-delete-a-row

QList items = table.findItems(.....);
QMap rowsMap;
for(int i = 0; i < items.count(); i++{
  rowsMap[items.at(i).row()] = -1; //garbage value
}
QList rowsList = rowsMap.uniqueKeys();
qSort(rowsList);

//Now go through your table and delete rows in descending order as content would shift up and hence cannot do it in ascending order with ease.
for(int i = rowList.count() - 1; i >= 0; i--){
  table.removeRow(rowList.at(i));
}
