Add parameter to Data table during run time

[switoo]

Hi all

Please help me to solve the below issue

I need to add a column name in data table during run time. My column name must start with a number. Ex:"71-18"

During run time the column name is added as "_7118" as header name should start with a letter.

Please let me know is there any other way to add a parameter with first letter as a number in Data table

i am getting the same error. the point is why are you trying to name the parameter starting with a number?
