dataTable的一般配置

dataTable的一般配置，mark一下，这玩意儿不好用。

    $('#dt_basic').dataTable({
	"bDestroy": true,
	"bFilter": false,
	"bLengthChange": false,
	"bPaginate": true,
	"pageLength": 100,
	"bProcessing": true,
	"sAjaxSource": reqUrl,
	"aoColumns": [
	    {"mData": "uid"},
	    {"mData": "opType"},
	    {"mData": "message"},
	    {"mData": "instanceName"},
	    {"mData": "optTimeStr"}
	],
	"order": [[0, 'desc']]
    });
