what is the mean of the first 2 and second 2 one of them mean number of column and what about second 2 mean, and other question is if i have to set 3 column width 20 and next three 30 and so on then i have to set same like that for each column or we can create variable for that and can use that variable if yes then how we can create variable please.

Thanks.

sheet.set_column(i, j, size).

Where i ,j = the column index and size= the size of the column

eg . sheet.set_column(0, 0, 20) to set the size of the first column to 20 and sheet.set_column(0, 1, 20) to set the size of the second column to 20
