And not get any data in layout. When i tried with table with 3-4 columns it was ok perfectly running but when i added more columns and data in table then data was not extracted. Can you please explain why this is happening.
How is your Excel table referenced in the your app? If you imported it using the "Add static data" (image below), then the table was "copied" to your app, and if you update the Excel spreadsheet you won't see any changes in your app - you'll need to import it again.
If you have your Excel file in a shared folder (such as OneDrive, Dropbox, Box, etc.), then you'll need to recreate the connection to your Excel file. When you add a data source pointing to such file, PowerApps will store the "schema" (name / type of columns) of the file locally, so it doesn't have to fetch it all the time.
