Not able to format data within a table

Anonymous  I cannot use edit queries to format the data, since my table is actually aggregating the data  i.e. for each employee, it is counting the number of times that employee has appeared in the dataset (Employee Name, COunt(Employee ID)). Since neither ID and Name are numbers, I cannot add comma seperator in the edit query tab. 

I would suggest creating a measure using count() and than use the modeling Tab

COUNT_Emp_id = COUNT('Table'(Emp_ID))
