"Code Note" Java repeatedly see the implementation of the project (1)--jtable, TableModel use

2. Javax.swing.table.TableModel and javax.swing.JTable
4. JTable, TableModel is the Java inside the picture form package.
6. TableModel: Provides table display data, table dimensions, table display data types, column headings, and other properties that the table needs to display
8. JTable: Provides properties and actions for the table itself, such as table style, row height, background, row check properties, and so on
10. JTable equivalent to Web pages, models, TableModel equivalent to servers, clothing.
12. JTable and TableModel are interdependent relationships (equal to B/s mode)

14. TableModel the role of the server, real data

16. JTable to show something TableModel provide it, refresh once to request once

18. Deal with the elimination of logic (algorithm implementation):

    1) The same image can be eliminated

    2) No obstructions can be eliminated in the same row or column

    3) A turning point to eliminate

    4) Two inflection points to eliminate

20. Look at the project ideas repeatedly:
    1. Build a good form;
    2. Adding JTable Components
    3. Adding TableModel Components
22. File directory:
