我正在使用jQuery数据表开发一个带有访问json对象方法的Web应用程序。这是我指定的代码
"aoColumns": [
{ "mData": '<input type="checkbox" value='+id+>'},
{ "mData": "email_address" },
]
我需要添加一个带id的checkbx。 但它没有用，请帮帮我

首先，您尚未发布完整的代码。
您可能需要参考mData文档。它只是从JSON数据属性中读取数据，包括嵌套数据对象。
或者，您可能需要考虑mRender，其中包含
此属性是mData的渲染合作伙伴，建议使用此属性 当你想操纵数据进行显示时（包括 过滤，排序等）但不改变基础数据 表，使用此属性。
但请查看以下示例，其中我使用了回调函数 fnRowCallback ，根据文档
此功能允许您在每行后“发布” 为每个表绘制生成，但在屏幕上呈现之前。 此函数可用于设置行类名等。
