JTable動態加載表格

JTable動態加載表格，數據是模擬的

public class LayoutTest extends JFrame {

表格的樣式設計：如，表格內容居中，設計斑馬線，字體的大小等等

public static void makeFace(JTable table) {
        DefaultTableCellRenderer renderer = new DefaultTableCellRenderer(){
            /**serialVersionUID*/
            private static final long serialVersionUID = 1234579841267L;

            @Override
            public Component getTableCellRendererComponent(JTable table,
                    Object value, boolean isSelected,boolean hasFocus,
                    int row, int column) {
                if(row%2==0){
                    setBackground(new Color(202,241,245));
                }else{
                    setBackground(new Color(255,255,255));
                }

                setHorizontalAlignment(JLabel.CENTER);// 表格內容居中
                ((DefaultTableCellRenderer) table.getTableHeader().getDefaultRenderer())
                .setHorizontalAlignment(DefaultTableCellRenderer.CENTER);// 列頭內容居中
                 table.getTableHeader().setFont(new Font("微軟雅黑", Font.PLAIN, 13));
                 table.getTableHeader().setResizingAllowed(true);
                 table.setRowHeight(26);//設置行高

                return super.getTableCellRendererComponent(table, value, 
                        isSelected, hasFocus, row, column);
            }
        };
        for (int i = 0; i < table.getColumnCount(); i++) {
            TableColumn col = table.getColumn(
                    table.getColumnName(i));
            col.setCellRenderer(renderer);
        }
        table.getTableHeader().setBackground(new Color(51, 102, 255));
    }

運行有結果如下：
