Show/Hide/Best fit
You can show or hide each one of the list's columns at your discretion. By selecting 'Remove This column' or by dragging the header downwards (a large X symbol appears) you can hide the selected column.
By selecting 'Column Chooser', a box that includes all hidden columns is shown in the lower right part of the list.
By dragging them from the list to the headers row, you can display them again.
By selecting 'Best fit (all columns)' or 'Best fit', the width of all the columns or each column respectively, will be automatically and optimally set, based on the properties of the corresponding field.
