## Class AutoResizeTableColumns

- java.lang.Object
- - gr.zeus.ui.table.AutoResizeTableColumns

- All Implemented Interfaces:
    java.util.EventListener, javax.swing.event.TableModelListener

      public final class AutoResizeTableColumns
      extends java.lang.Object
      implements javax.swing.event.TableModelListener

  NOTE: This class needs a lot of testing in order to check all possible use cases! Please use `setDebugMode(true)` and reports any bugs or malfunctions to gregkotsaftis@yahoo.com

  This class can be used to dynamically resize a `JTable`, every time it's data changes, based on header size and row data. It can also lock any or all of the table's columns (no manual resize possible). Please note that this class respects hidden columns (columns with all sizes set to zero) and excludes them from the resize. Also take into consideration that if performance is a must, you should avoid adding and removing single rows in the table's model, to avoid multiple tableChanged() events leading to multiple executions of this class. Instead you should store your data in Vectors and pass them on to the table's model in a single step. Finally, you can use the method `setDebugMode(true)` in order to understand how this class functions and the results of your own application; note that if you enable debuging, the performance will degrade by a major degree!
