[PATCH] Simple pivot support

Reported by: ruport Assigned to: sandal
Milestone: ruport 1.4 defects Keywords:
Cc: ryan@platte.name

Description

This adds test-driven support for a Ruport::Data::Table#pivot method.

It's called thusly:

table.pivot('group_column', 'pivot_column', 'summary_column', :pivot_order => pivot_column_ordering_spec)

and returns a new table whose columns are the unique values of pivot_column, in the order specified by pivot_column_ordering_spec, populated with the correlated values in summary_column.

I uploaded a second draft of this patch. It

  • changes Table#pivot to an option-based syntax
  • removes unnecessary tests
  • changes tests that depended on the output of the string formatter to instead just compare equality with another Table, and
  • adds API documentation with an example.
