使用arrayList值将行值填充到SWING JTable JAVA

Question

for (int v = 0; v < values1.size(); v++) {

            values2.add(values1.get(v));
        }

       Object jFill[] = values2.toArray();

        model.addRow(jFill);

谢谢你。

在这里，我的完整工作表模型工作，您可以添加行，移除行和更改值。

您可以轻松地向帧中添加：

    protected MyTableModel mytableModel = new MyTableModel();
    scroll = new JScrollPane(mytableModel);

table类：
