QTableWidget 导出到csv表格

  跳槽到了新的公司，开始苦逼的出差现场开发，接触到了新的应用。有很多应用需要将Table导出成表格，可以把table导出成csv格式的文件。跟大伙分享一下；

    private slots:
        void addRowSlot();
        void delRowSlot();
        void exportSlot();
};

    : QDialog(parent, flags)

    ui.setupUi(this);

     QTableWidgetItem * item = new QTableWidgetItem("0");
    ui.m_pTable->setHorizontalHeaderItem ( 0, item );
    item = new QTableWidgetItem("1");
    ui.m_pTable->setHorizontalHeaderItem ( 1, item );
    item = new QTableWidgetItem("2");
    ui.m_pTable->setHorizontalHeaderItem ( 2, item );
    item = new QTableWidgetItem("3");
     ui.m_pTable->setHorizontalHeaderItem ( 3, item );
