Qt 将TableWidget表格数据保存到Excle详细介绍

结果图：

 

 

 

需要的头文件

 需要根据小伙伴的数据进行变更，下面是tableWidget控件表格的数据保存到Excle

 

 

 

附上代码：

ui->progressBar->show();    //进度条需要在ui文件中加个progressBar控件

    ui->progressBar->setValue(0);   //设置进度条的值为0

    QString fileName = QFileDialog::getSaveFileName(this,tr("Excle file"),QString("./paper_list.xls"),tr("Excel Files(*.xls)"));    //设置保存的文件名

    if(fileName != "")

    {

         ui->progressBar->setValue(10);

         QAxObject *excel = new QAxObject;

         if(excel->setControl("Excel.Application"))

         {

             excel->dynamicCall("SetVisible (bool Visible)",false);

             excel->setProperty("DisplayAlerts",false);

             QAxObject *workbooks = excel->querySubObject("WorkBooks");            //获取工作簿集合

             workbooks->dynamicCall("Add");                                        //新建一个工作簿

             QAxObject *workbook = excel->querySubObject("ActiveWorkBook");        //获取当前工作簿

             QAxObject *worksheet = workbook->querySubObject("Worksheets(int)", 1);

             QAxObject *cell;

             /*添加Excel表头数据*/

             for(int i = 1; i <= ui->tableWidget->columnCount(); i++)

             {

                 cell=worksheet->querySubObject("Cells(int,int)", 1, i);

                 cell->setProperty("RowHeight", 40);

                 cell->dynamicCall("SetValue(const QString&)", ui->tableWidget->horizontalHeaderItem(i-1)->data(0).toString());

                 if(ui->progressBar->value()<=50)

                 {

                     ui->progressBar->setValue(10+i*5);

                 }

             }

             /*将form列表中的数据依此保存到Excel文件中*/

             for(int j = 2; j<=ui->tableWidget->rowCount()+1;j++)

             {

                 for(int k = 1;k<=ui->tableWidget->columnCount();k++)

                 {

                     cell=worksheet->querySubObject("Cells(int,int)", j, k);

                     cell->dynamicCall("SetValue(const QString&)",ui->tableWidget->item(j-2,k-1)->text()+ "\t");

                 }

                 if(ui->progressBar->value()<80)

                 {

                     ui->progressBar->setValue(50+j*5);

                 }

             }

             /*将生成的Excel文件保存到指定目录下*/

             workbook->dynamicCall("SaveAs(const QString&)",QDir::toNativeSeparators(fileName)); //保存至fileName

             workbook->dynamicCall("Close()");                                                   //关闭工作簿

             excel->dynamicCall("Quit()");                                                       //关闭excel

             delete excel;

             excel=NULL;

             ui->progressBar->setValue(100);

             if (QMessageBox::question(NULL,QString::fromUtf8("完成"),QString::fromUtf8("文件已经导出，是否现在打开？"),QMessageBox::Yes|QMessageBox::No)==QMessageBox::Yes)

             {
