2D matrix for x2many fields
===========================

This module allows to show an x2many field with 3-tuples
($x_value, $y_value, $value) in a table

          $x_value1   $x_value2 
========= =========== ===========
$y_value1 $value(1/1) $value(2/1)
$y_value2 $value(1/2) $value(2/2)
========= =========== ===========

where `value(n/n)` is editable.

An example use case would be: Select some projects and some employees so that
a manager can easily fill in the planned_hours for one task per employee. The
result could look like this:

The beauty of this is that you have an arbitrary amount of columns with this widget, trying to get this in standard x2many lists involves some quite agly hacks.

Usage
=====

Use this widget by saying::

<field name="my_field" widget="x2many_2d_matrix" />

This assumes that my_field refers to a model with the fields `x`, `y` and
`value`. If your fields are named differently, pass the correct names as
attributes::

<field name="my_field" widget="x2many_2d_matrix" field_x_axis="my_field1" field_y_axis="my_field2" field_value="my_field3" />

You can pass the following parameters:

field_x_axis
    The field that indicates the x value of a point
field_y_axis
    The field that indicates the y value of a point
field_label_x_axis
    Use another field to display in the table header
field_label_y_axis
    Use another field to display in the table header
field_value
    Show this field as value
show_row_totals
    If field_value is a numeric field, calculate row totals
show_column_totals
    If field_value is a numeric field, calculate column totals

Known issues / Roadmap
======================

* it would be worth trying to instantiate the proper field widget and let it render the input
