如何使用socket.io在datatable的status列中显示已下载文件的百分比

如何使用socket.io在datatable的status列中显示已下载文件的百分比,socket.io,datatables,Socket.io,Datatables,我如何才能在数据表的状态列中获得%。我真的被困在这里了。有人能帮我解决这个问题吗 socket.on( 'message', function( data ){ console.log(data); var percentage = data.percent; 我必须在此处插入百分比,以便它将显示在datatable的状态栏中的百分比中: {"sTitle":"Status",align: 'Center', "mData": null, "bSortable": false

我如何才能在数据表的状态列中获得%。我真的被困在这里了。有人能帮我解决这个问题吗

socket.on( 'message', function( data ){
    console.log(data);
    var percentage = data.percent;
我必须在此处插入百分比,以便它将显示在datatable的状态栏中的百分比中:

 {"sTitle":"Status",align: 'Center', "mData": null, "bSortable": false, "sClass": "head1", "sWidth": "75px",
                "render": function (data, type, row, meta) {
                  if (data.IsDirectory) {
                     return  "";
                 }else{
                   return "";

                 } 
                }
              }
