如何使用数据表中的aoColumn sTitle属性获取多个列标题名称

Question

我只能提供一个sTitle Name.But我想获得两个列标题名称。一个是＆＃34;文件名＆＃34;另一个是＆＃34;日期＆＃34;在dataTable中使用aoColumn sTitle属性。

我怎样才能做到这一点。任何人都可以帮助我......

app.js中的代码：

        "aoColumns": [{"sTitle":"File Name", "mData": null, "bSortable": false, "sClass": "head0", "sWidth": "55px",
            "render": function (data, type, row, meta) {
              if (data.IsDirectory) {
                return "<a href='#' target='_blank'><i class='fa fa-folder'></i>&nbsp;"  + data.Name +"</a>";
              } else {
                return "<a href='/" + data.Path + "' target='_balnk'><i class='fa " + getFileIcon(data.Ext) + "'></i>&nbsp;" + data.Name +" "+data.Date+"</a>";
              }
            }
          },

         {"sTitle":"Date", "mData": null, "bSortable": false, "sClass": "head0", "sWidth": "55px",
            "render": function (data, type, row, meta) {
              if (data.IsDirectory) {
                return data.Date;
              } else {
                return data.Date;
              }
            }
          }
        ]   
     };

我的app.js：
