Click any column header and select Manage columns.
Or scroll all the way to the right and click the plus sign (+) at the top of the last column.
Click Custom Column.
Select the column type that fits your data, such as text, number, or date.
Type the name of your field and click Create.
Once created, the new column will appear in your view. You can edit your profile view at any time to rearrange these columns.
