Question

我想要3个按钮 - 下载csv，xls和pdf文件。在我的情况下，当我点击下载csv文件按钮时，它会保存csv文件的扩展名，但是当我打开它时它是excel - 它不是逗号分隔文件。 PDF下载按钮工作正常。 xls按钮不起作用 - 它根本不可点击。我试着写这段代码：

"TableTools": {
     "aButtons": [ {
          "sExtends":    "download",
          "sButtonText": "Download XLS",
          "sUrl":        "/generate_xls.php"
      }]
 }

然后每个按钮下载excel文件。

这是我的代码：

使用此方法时，您需要定位所有需要的按钮。只是让"xls"打破了它。

aButtons: [
    { sExtends: "csv",
      sFileName: 'download.csv',
      sFieldSeperator: "," //<--- example of how to set the delimiter
    },
    { sExtends: "xls",
      sFileName: 'download.xls'
    },
    { sExtends: "pdf",
      sFileName: 'download.pdf'
    }   
]
