A view consists of a number of potential elements:
A screen (the right side typically, but may include splits. Also includes
any special formatting for that screen such as modified barstyles etc.)
A table (the data displayed on the right side
A group (optional)
A filter (typically "All tasks" but may be anything you want)
Different views may access the same table or group or filter or screen but
may use a different combination.
Modifying a table will affect all views which use that table.
For this reason, and because I frequently add/remove columns, it is good
practice to build a specific table for each view. For example you might
build a presentation view which uses a table and filter customized to show
only the elements you want to present, or a print view etc.
The data displayed in the table or view does not belong to the table. It is
present in the file and is only displayed in the table, so deleting columns
in the table does not delete that information. Deleting a row however will
delete the information.
