javascript - jQuery dataTable 错误无法读取未定义的属性 'mData'

Question

我有以下包含 6 列的数据表。

渲染表格后，我正在初始化 .DataTable()。但是得到错误:

'mData' of undefined TypeError: Cannot read property 'mData' of undefined

正如一些帖子中提到的，我已经添加了 tfoot 但仍然有错误。

$(document).ready(function() {
    $('#pTable').DataTable();
});

Answer 1

您有 6 个 th，但在两行中都有 7 个 td。 th 的数量必须与 td 的数量匹配。添加一个隐藏的 th 修复它

$(document).ready(function() {
    $('#pTable').DataTable();
});
