If you don't change this setting, the default view is always the table/grid view, showing all of your data, dependent of course, on your Security
On the Develop > Table Settings
page, there is a field called "Defaultview" with a drop-down list that lets you choose among the many Views
(these are basically page templates) in your application to set which one is the default for that table. This is handy if you want people to see your table laid out in a particular way.
