我想要 3 个按钮 - 下载 csv、xls 和 pdf 文件。在我的例子中，当我点击下载 csv 文件按钮时，它保存为 csv 文件的扩展名，但是当我打开它时它是 excel - 它不是逗号分隔的文件。 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:

当您使用这种方法时，您需要定位所有需要的按钮。只要有一个 "xls" 就可以打破这一切。
aButtons: [
{ sExtends: "csv",
sFileName: 'download.csv',
sFieldSeperator: "," //<--- example of how to set the delimiter
},
{ sExtends: "xls",
sFileName: 'download.xls'
},
{ sExtends: "pdf",
sFileName: 'download.pdf'
}
]
