//将列配置复制给第二个参数的键值 export_cols
//控件会将选择的列数据post至url,可通过I('post.exportCol')获取，再进行数据筛选逻辑处理。
$builder->addTopButton('export', array('export_cols' => $cols_options, 'title' => '样例导出', 'data-url' => U('/admin/post/export'), 'data-filename' => '文章列表', 'data-streamrownum' => '10'));

// antd-admin table action
/** @var \AntdAdmin\Component\Table\ActionsContainer $container */

 $export_arr = [
    ['sheetName' => 'Sheet1', 'url' => U('/admin/post/export'), 'rownum' => '15'],
    ['sheetName' => 'Sheet2', 'url' => U('/admin/post/export'), 'rownum' => '15'],
 ];
 
 $builder->addTopButton('export', ['data-url' => json_encode($export_arr), 'data-filename' => '导出列表', 'data-streamrownum' => intval($export_arr[0]['rownum'])]);

可在导出数据处理的action位置进行错误验证，使用$this->errro("test")
插件可自动获取错误信息并alert提示用户

每一行数据添加字段 _cellProperties 来配置对应的单元格需要合并的范围。

_cellProperties 包括 rowSpan colSpan值，为0表示被合并的单元格
