The Access 2007 Tasks Database template is ready to use the first time that you open it, but you can also customize the database to better suit your needs.
Customize the Tasks database by adding a new field to the Tasks table, and then adding that field to the Task List form, the Task Details form, and the Task Details report.
Add a field to the Tasks table
Close all open tabs.
In the Navigation Pane, double-click the Tasks table.
Scroll to the right until you see the column named Add New Field. Double-click the column heading, and then type in the field name.
The first time you enter data in the column, Access sets the data type for you.
Add a field to a form or report
Once a field has been added to a table, you can then add it to a form or report.
Right-click the form or report in the Navigation Pane and then click Layout View.
On the Format tab, in the Controls group, click Add Existing Fields.
Drag the field you want from the Field List to the form or report.
