public class DataTable

extends Servlet

A DataTable is a simple component intended to be used as an embedded servlet which shows tabular data. Closely related to List, q.v. Expects to find the following parameters in the context (in addition to the normal ones which allow connection to the database):

query

A valid query against the database

select_action

The URL to follow when an item is selected

id_column

The column whose value should be appended to the select_action URL to select a particular data item

link_column

The column to use as a link.

  Revision 1.5.4.1  2005/12/23 10:48:33  simon
  Brute force tidy up after CVS server crash: this time it should work.

  Revision 1.5  2003/08/20 09:38:35  simon
  Code cleanup with eclipse; mostly removal of exccessive includes

  Revision 1.4  2001/11/20 10:46:48  simon
  Err... nothing's actually changed; the CVS is lying

  Revision 1.3  2000/10/20 16:11:04  simon
  Changes in line with re-usable, thread-safe ResultFormatter.

  Revision 1.2  2000/10/18 09:57:16  simon
  Changes to ResultFormatter and friends to make table headers switchable.

  Revision 1.1  2000/10/16 12:09:49  simon
  New files: DataTable, an embedded servlet similar to List;
  FileMaybeUploadWidget, a widget to allow files to be uploaded (not yet
  working); URLWidget, a widget which validates the format of submitted
  URLs and can optionally link-check them.
