First off - I am more than experienced at report building. But when it comes to a sheet that has 250+columns, picking the columns in order you want them in your report is very tedious. The other option is click and add lots of columns and then drag them into their right sport/order, which is even more tedious.
There should be way to look at the dropdown of selectable columns in the order they are in your sheet (left to right). If this is possible, then I am unaware. That type of column view happens in other operations in Smartsheet.
Thanks
