Summary lines in tables
Table views can display a summary line, to show aggregate values for columns.
To get a summary line in a table, define aggregate field item tags at the bottom of the
TABLE
container, with the corresponding AGGREGATE
form item
definitions in the ATTRIBUTES
section.
Define the type of the aggregate field with the AGGREGATETYPE
attribute: The
aggregate value can be automatically computed, or set by program.
To get a global label for the summary line, specify the AGGREGATETEXT
attribute at the
TABLE
level. This aggregate label will appear on the left in the summary line, if
no aggregate text is defined at the aggregate field level.
To decorate the summary line, use presentation style attributes such as summaryLineAlwaysAtBottom
.
total

table:
TABLE (AGGREGATETEXT="Total")
{
[c1 |c2 |c3 ]
[c1 |c2 |c3 ]
[total ]
}
