5.3.3. Limiting the Number of Rows on a Table Page
By default, the Table and Table-Form layouts will display all existing rows in the table.
For large tables, this might be undesirable. You can limit the number of rows to be
displayed at once, and generate a dropdown list to navigate to another range of rows
within the table together with 'next' and 'previous' hyperlinks:
1. Check the Use Table Range? property for the group in the Application
Definition editor.
2. Set the Table range size property to the number of rows you want to display at
once.
The above example shows the Countries group with the Use Table Range? property set
to true, and the Table range size set to 6. You can now see that a dropdown list has been
generated to select other sets with records, and Previous and Next hyperlinks to navigate
to the next or previous record set in the table.
5.3.4. Adding Summary Information to a Table
For numeric columns, you can add summary information in the table footer. You can
choose from 3 types:
1. Sum
2. Average
3. Count
The summary will be displayed in the table footer. The label of the table footer is by
default Total, but you can change that in the Resource Bundle (see Chapter 11
"Internationalization and Messaging").
