You should read up on selectors and how to work with their various elements.
Your issue is lacking detail for anyone to really help so as a guess you could look at using the Find Children activity.
This can be used to return all selectors present in the column you have highlighted to a datatable. You can then filter this to just those which contain the key words you need (you are likely going to be looking at accessing something like the ‘aaname’ element for this task).
Once you have your results, you can take the full selector and grab all the details present on that row by analysing which are the common elements for each column, such as ‘rownumber’ maybe. It all depends on your application, however, the process is the same.
There are a number of posts on the forum showing use of FindChildren.
