No, you don't do that. First of all, a table is an unordered entity, so you cannot add rows on "top". You can add rows, but they will just be there somewhere.
And, second, a table contains data, not metadata. The first column, for instance, seem to have numeric values. RPT would be out of there.
What you want is to have the columns to be named RPT, WKSHT,LINE,CLMN and AMT rather than 667603, S20001, 0030, 0040 and 1, which are quite weird column names. (And presumably you want that data to be in the table).
I don't know exactly what means you use to import the file, but make sure you create the table first, or at least specify the column names. And make sure that you deselect any option about "my file has column names".
