Hi Pradeep,
Can you upload the Xpath of 2 or 3 cells than we can make a strategy to solve you issue,
meanwhile, i believe there two conditions are possible i.e..
1.All cell have same xpath-> In this case you can use
List element=driver.findElements(By.xpath("xpath")); , it will return list of all cell,
- Cell have different xpath :You can write Relative xpath to perform any action.
I think it will work please let me know you side.
Thanks
