With your data, you may want to remove or hide a few columns to make the data easier to look at. Here's how to do it.
First, click the Add Transform button and choose the Select Column transform. This will bring up a list of all of the columns in your data.
Instead of choosing columns to delete, you'll choose the ones you want to see, and then hit Run. If you have a long list of column names, you can use the search bar to start typing in the columns you know you'd like to keep to navigate to them faster.
