24             for(int i = 0; i < table.getColumnCount(); i++) {
25                 table.getColumn(table.getColumnName(i)).setCellRenderer(tcr);
26             }
27             tcr.setHorizontalAlignment(JLabel.CENTER);
28         }
29         catch (Exception e){
30             e.printStackTrace();
31         }

将其中的Table换成你自己创建的Tabel就好了。
