How do I enter text in web automation for column name being generated dynamically(for ex., based on 2 date selected the column gets created)?

I need to enter data in a text box which is in table format. The column name gets changed after page load, based on some value column name is dependent ( basically column name is dynamic) so how do I enter the data into those respective column, I’m catching data from excel sheet.

I hope the table in which you are entering data has a selector
please try to make the selector value as a dynamic value with aaname={{the dynamic column name}}
Can you share the screen shots of the value of textbox properties you are entering ?

Thanks for the reply,

i want to enter data based on the column name instead of tableCol value
