I'm want to use a QTableView with a QSqlTabkeModel. The table's content is invisible after seting up the model.
The QTableView widget is created in designer.

initalizeModel test method is from http://doc.qt.nokia.com/stable/sql-tablemodel.html
Qt Code: 
  1. void DatabaseWindow::initializeModel()
  2. {
  3.     mDataTableModel->setTable("person");
  4.     mDataTableModel->setEditStrategy(QSqlTableModel::OnRowChange);
  5.     mDataTableModel->select();
  6.  
  7.     mDataTableModel->setHeaderData(0, Qt::Horizontal, QObject::tr("ID"));
  8.     mDataTableModel->setHeaderData(1, Qt::Horizontal, QObject::tr("First name"));
  9.     mDataTableModel->setHeaderData(2, Qt::Horizontal, QObject::tr("Last name"));
  10.  
  11.     //here i call ExtendedTableWidget's setUpView method
  12.     mTableWidget->setUpView(mDataTableModel);
  13. }
To copy to clipboard, switch view to plain text mode 

header:
Qt Code: 
  1. namespace Ui
  2. {
  3.     class ExtendedTableWidget;
  4. }
  5.  
  6. class ExtendedTableWidget : public QWidget
  7. {
  8.     Q_OBJECT
  9. public:
  10.     explicit ExtendedTableWidget(QWidget *parent = 0);
  11.  
  12.     void setUpView(QSqlTableModel *model);
  13.  
  14. private:
  15.  
  16. private:
  17.     Ui::ExtendedTableWidget *mUi;
  18. };
To copy to clipboard, switch view to plain text mode 

cpp:
Qt Code: 
  1. #include "extendedtablewidget.h"
  2. #include "ui_extendedtablewidget.h"
  3.  
  4. ExtendedTableWidget::ExtendedTableWidget(QWidget *parent) :
  5.     QWidget(parent),
  6.     mUi(new Ui::ExtendedTableWidget())
  7. {
  8.     mUi->setupUi(this);
  9. }
  10.  
  11. void ExtendedTableWidget::setUpView(QSqlTableModel *model)
  12. {
  13.     mUi->tableMainData->setModel(model);
  14.     mUi->tableMainData->setSelectionModel(new QItemSelectionModel(model));
  15.  
  16.     //the tpmTable is show the content, but tableMainData isn't
  17.  
  18.     QTableView *tpmTable = new QTableView();
  19.  
  20.     tpmTable.setModel(model);
  21.     tpmTable.show();
  22. }
