[{"L1_INJ", "GWIR"} is a unique column identifier. You can reformat it as you please. The identifier is used as a data function argument in vdata[...], which is populated in the Table.

comment How do you round numbers so that it affects computation?
Nice observation. That also occurs with 481/100. but not with N[481/100] so the safer usage is to round to integer like N[Round[100*4.811]/100]
