Lists in a
report can be output using three bands: Header
, Footer
, and Data
. Data are output using
these bands. The basic band is the Data
band. A data source is
specified to each Data
band. The data
source is a table. Each data source has data fields. It is possible
to output a table by placing text components with references to
these fields. One data source can specify previously unknown number
of rows with data. The Data
band is output
as many times as there are rows in the specified data source. For
example, if there are 100 rows in the data source, then the
Data
bad will be
output 100 times. If it is not enough space on one page, the second
page will be generated and printing will be continued. Using
the Header
band, headers
will be added to the table that is output using the
Data
band. Correspondingly,
the Footer
band is used
to output different totals by the output table.
