Choosing Visible Columns

How do I choose which columns are visible and which not?

In each section (Previous invoices, Active invoices and Next invoices), you can edit the view by choosing which columns are visible and which are not.

1. Click the wheel at the end of the column header.
   
   
   
   
2. Click a column name written in grey to add it or a column name written in white to hide it. If an invoice is missing mandatory data and this column is hidden, the column is highlighted with a red exclamation mark. 
   
   
   
   

3. If a value inside a column is not fully visible, double-click on the value to see the entire contents of the column.
