同意楼上的看法，java是典型的mvc结构(model-view-control)，数据都放在model中处理。

[小凤哥]

建立表格的一个例子：
Object[][] data = {
{"Mary", "Campione",
"Snowboarding", new Integer(5), new Boolean(false)},
{"Alison", "Huml",
"Rowing", new Integer(3), new Boolean(true)},
{"Kathy", "Walrath",
"Chasing toddlers", new Integer(2), new Boolean(false)},
{"Mark", "Andrews",
"Speed reading", new Integer(20), new Boolean(true)},
{"Angela", "Lih",
"Teaching high school", new Integer(4), new Boolean(false)}
};

String[] columnNames = {"First Name",
"Last Name",
"Sport",
"# of Years",
"Vegetarian"};

final JTable table = new JTable(data, columnNames);
有空了多看看jdk的api，ok？

我的一个经验是，如果要改变table 的行和列，不如用tablemodel好。你可以通过setmodel方法动态的指定table的内容。
