5.3.1. Hide Items in a Table
The generated page looks as follows:
Attention: The order of the rows in the table is determined by the Order By
clause in the View Object. See section 3.3.5 - Determining the Order of
Displayed Rows.
The remainder of this section discusses the following topics that are related to table
layouts:
• Hide Items in a Table
• Allowing the User to Sort Data in a Table Page
• Limiting the Number of Rows on a Table Page
• Adding Summary Information to a Table
• Change Table-Related ADF Business Components Settings for performance
tuning
• Using Table Overflow
With the Display in Table Layout? property, you can determine which items will be
generated in the table. Values and meaning are the same as for the Display in Form
Layout? property (see section 5.1.1 - Hide Items on the Form Page).
So when you do not want an item to be generated in a table page but you do want to
show that item in a form page, set Display in Table Layout? to false.
5.3.2. Allowing the User to Sort Data in a Table Page
It is possible to generate a feature where the user can do an online sort of the records
queried in a table. The user can simply click on the column header and then the table
content is sorted based on the values in this column. Clicking the same column header
twice will switch the sort order from ascending to descending and vice versa.
If this is required, then you must set the Column Sortable property on the item level to
true, for those items you wish to be sortable.
