Coding data Into a dataset and then displaying it in a table

as for saving it, would that solve my problem. The first problem I am trying to address is putting AAL % change in row 1 column 2,
UAL % change in row 2 column 2,
and DAL % change in row 3 column 2. I don’t believe I have written or am aware of code that allows me to input the data into the different rows. thanks for all your help
