/**** class CollapsibleTables.js | |||
* (c) 2008 by Patrick Westerhoff [poke] | |||
* | |||
* This class allows to make tables collapsible and adds a show/hide button to | |||
* affected tables. Tables which class attribute contains 'collapsible' or | |||
* 'expandable' are affected by this class and can be collapsed; the latter | |||
* automatically hides the content of all sections. | |||
* Header rows are used to divide the table into sections which can be collapsed | |||
* separately. By default the first row of the table is interpreted as a header | |||
* row, however this can be overwritten by adding 'collapsible' to the class | |||
* attribute of header rows. You can also hide a section individually by default | |||
* when in 'collapsible' mode by using 'expandable' as the row's class name | |||
* instead. | |||
