我正在通过任何查询来创建动态表的任务，到目前为止，我已经完成了所有任务，但停留在选择行的位置，当选择任何行时，将显示第0行no及其值返回行。

我对设置行键的理解很困惑，也无法在表中设置Sr.固定列，因此代码始终在固定列中返回0。请提出一些解决方案。
尽管我仍然无法通过行选择来做到这一点，但是我通过将Sr No设置为按钮并通过该按钮调用行选择来解决了问题，我已经在上面上传了完整的代码。
<p:column width="50">
<f:facet name="header">
<h:outputText value="Sr." />
</f:facet>
<p:commandButton style="width: 49px" action="#{liveRangeService.onRowSelect(rowindex)}"/>
</p:column>
此外，由于过滤器和排序影响序列号，因此给出错误的行号，我在填充tableData之后设置了filtereddata；
filteredData=tableData;
[如果有人可以建议通过行选择而不是命令按钮进行所有选择，则我会很乐意。
