当前，我正在开发仪表板，该仪表板允许用户过滤数据并向服务器中存在的CSV文件添加注释并添加注释。为此，我使用了不同类型的过滤器，并尝试将bootstrap excel表过滤器插件和jquery数据表插件集成为日期过滤器。问题是，当我从引导过滤器下拉菜单中应用过滤器时，它会过滤数据并出现异常，如下所示。
excel-bootstrap-table-filter-bundle.js:274 Uncaught TypeError: Cannot read property 'innerText' of undefined

When selecting date filter getting another exception,
