问题描述
我想有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，它保存与csv文件的扩展，但当我打开它是excel - 它不是逗号分隔的文件。 PDF下载按钮正常工作。 xls按钮不工作 - 它是不可点击的。我试着写这个代码：
I want to have 3 buttons - to download csv, xls and pdf file. In my case when I click on the download csv file button, it saves with extension of csv file, but when I open it it is excel - it's not comma separated file. PDF download button is working correctly. xls button does not work - it's not clickable at all. I tried to write this code:
"TableTools": {
"aButtons": [ {
"sExtends": "download",
"sButtonText": "Download XLS",
"sUrl": "/generate_xls.php"
}]
}
但是每个按钮都会下载excel文件。
But then each button download excel file.
这是我的代码：

当您使用此方法时，您需要定位所有所需的按钮。
You need to target all desired buttons, when you are using this approach. Just having a "xls" breaks it all up.
aButtons: [
{ sExtends: "csv",
sFileName: 'download.csv',
sFieldSeperator: "," //<--- example of how to set the delimiter
},
{ sExtends: "xls",
sFileName: 'download.xls'
},
{ sExtends: "pdf",
sFileName: 'download.pdf'
}
]
