Java reorganizable grid

How about a JTable?

Your criteria:

  • A list of data – yes. A table model can be as simple as an Object[][] or as complex as a custom class.
  • Reordering by clicking header – yes. You can use a TableRowSorter to sort when the column header is clicked.

For information on tables, see the "How to Use Tables" section of The Java Tutorial.

This document also has a section, "Sorting and Filtering", that talks about sorting with the column header. Here's an excerpt:

Table sorting and filtering is managed by a sorter object. The easiest way to provide a sorter object is to set autoCreateRowSorter bound property to true:

JTable table = new JTable();

This action defines a row sorter that is an instance of javax.swing.table.TableRowSorter. This provides a table that does a simple locale-specific sort when the user clicks on a column header. This is demonstrated in, as seen in this screen shot:
