先看插件说明，再看options的设置即可.
排序主要看：

sorter:numberSort

导出文件格式化主要看：

showExport:true,
            exportOptions:{
            	fileName:"例子后端常规监控",
            	worksheetName:"例子后端常规监控",
            	onCellData:function(cell, row, col, data){
            		if(row == 0){
            			return data;
            		}else{
            			return data.replace(/\([^\)]*\)/g,"");
            		}
                }
            },
