Introduction

This is very simple widget for Tablesorter - a JQuery plugin; used for grouping (and optionally collapsing) rows of sorted table. All script is very simple, automated and chaotic - but works.

Installation

$("table.tablesorter").tablesorter({ 
  widgets: ['groups'],
  emptyGroupCaption: "(none)",
  collapsableGroups: true
});

Value of first extending setting (emptyGroupCaption) is used as description of empty groups, eg :

Next one (collapsableGroups) is setting ability to collapsing single group - like this :

A special effect is the digit, which indicates number of collapsed rows.
