I have 6 columns ( 3 columns with text data, 3 more columns with numeric data ) in a data frame I need to read 3 columns (which is numeric) for now and when extra column added (numeric data) to the file dynamically my code has to read that column
I do not understand what it is you are trying to do exactly. If you have the 6 columns already in a data frame, what do you mean by dynamically reading the data?
