Could you pleases check in Uiexplorer whether any attribute is there like colnum or something which is represtnign the column number? If yes you can use that column number and row number to get the data.
Else use the anchor base. Anchor you can use as the header of the table.
You can use App/Web recorder and during recording you can choose the column header as the anchor.
@Abang_Jamuri_Abang_Shoker I see that selector has attribute of type role is table. If there is table then there should be column name also present in the selector
First, identify the element using selector
Then, open the selector in UiExplorer
Check is there any column name in the right side attributes
If its there enable that column name into your selector and validate the selector
