//页面调用渲染
var columns = [

        {"title": "名称", "mData":"evname" },
        {"title": "code", mData:'code',createdCell:formatCode},
         {"title": "创建者", "mData": "creator_uid"},
        {"title": "创建时间", "mData": "create_time"},
        {"title": "{{_('table_base_operate')}}", "mData":"id",createdCell: formatOption}

var params = {};  //传的参数
commonDataTables("risk-table", url, columns, params, true, true)


//最后一个true表示table要进行排序，传false表示不排序

在不排序的情况下，我们对列的自定义如 formattype 就可以了，直接定义mData为function
function formattype(data) {
    var str = data['status'] == 1?"启用":"禁用";
    return str;
};

需要排序的情况下，使用上诉方式会报错，原因是该列的关键字段成了一个函数，无法找到

所以我们使用下面的方式进行自定义列的内容 - 要在column中保留mData对应的显示的字段，自定义渲染的内容通过createdCell的方法

function formatCode(cell,celldata,data) {
    var status = data['status'];
    var str = status==0?"初始化":status==1?"试运行":status==2?"进行中":"禁用";
    $(cell).html(str);
};
