3. js渲染数据的代码

table.render({
        elem: '#test'
        ,method: 'GET'
        ,url:'/api/students'
        ,toolbar: '#toolbarDemo'
        ,title: '用户数据表'
        ,totalRow: true
        ,cols: [[
            {type: 'checkbox'}
            ,{field:'id', title:'ID', 80, fixed: 'left', unresize: true, sort: true, totalRowText: '合计'}
            ,{field:'name', title:'姓名', 120, edit: 'text'}
            ,{field:'age', title:'年龄', 80, sort: true, totalRow: true}
            ,{field:'sex', title:'性别', 80, edit: 'text', sort: true}
            ,{fixed: 'right', title:'操作', toolbar: '#barDemo', 150}
        ]]
        ,page: true
        ,parseData: function(res){ //res 即为原始返回的数据
            return {
                "code": res.code, //解析接口状态
                "msg": res.msg, //解析提示文本
                "count": res.count, //解析数据长度
                "data": res.data //解析数据列表
            };
        }
    });
    

【解决方式】

1. 把col后面的[[]]变为

[
    [
        //TODO
    ]
]

原因: 因为[[…]]之间的表达式在thymeleaf被认为是内联表达式,所以渲染错误
