Qt--玩转Excel

Excel表格在日常工作中使会经常用的，有时候程序中需要生成测试报告就需要用到Excel，在此封装了一个类QExcel，方便后续使用。示例如下：

excel = new QExcel(); //新建对象excel->open("C:\\Users\\Administrator\\Desktop\\www.xls"); //打开一个Excel文件
for (int i=1; i<=10; i++)
{for (int j=1; j<=10; j++){excel->setCellString(i,j,QString::number(i+j));}
}
excel->setCellBackground(1,1,Qt::red);
excel->setCellBackground(2,2,Qt::green);
excel->setCellBackground(3,3,Qt::blue);
excel->setCellBackground(4,4,Qt::yellow);
excel->setCellBackground(5,5,Qt::gray);
excel->save(); //保存文件//=================================================================
注意：
1、打开文件和创建文件，二选一，即可使用所有提供的功能；
2、操作完成之后记得保存文件（调用save()函数）和退出Excel（调用quit()函数）
3、行、列都是从1开始，填0行0列，程序崩溃
//=================================================================excel->createFile("C:\\Users\\Administrator\\Desktop\\Test.xls"); //创建一个Excel文件
for (int i=1; i<=10; i++)
{for (int j=1; j<=10; j++){excel->setCellString(i,j,QString::number(i+j));}
}
excel->setCellBackground(1,1,Qt::red);
excel->setCellBackground(2,2,Qt::green);
excel->setCellBackground(3,3,Qt::blue);
excel->setCellBackground(4,4,Qt::yellow);
excel->setCellBackground(5,5,Qt::gray);
excel->save(); //保存文件excel->quit(); //退出Excel

需在.pro工程文件中添加axcontainer库

QT       += axcontainer
