Report templates¶

To create a report, you must first prepare a report template in LibreOffice Calc.

The template files are located in the report folder of the project directory.

The following figure shows a template of the Invoice report.

Reports in Jam.py are band-oriented.

Each report template is divided into bands. To set bands use the leftmost column of a template spreadsheet.

In the Invoice report template there are three bands: title, detail and summary.

In addition, templates can have programmable cells.

For example, in the template of Invoice report the I7 cell contains the text %(date)s.

Programmable cell begins with %, then follows the name of the cell in the parenthesis which is followed by character s.
