java读取数据库并显示二维数组并用table表格显示

Object[][] readuser() {
			Object[][] tableuser = null;
			try {
				conn();
				int count=0;
				String sqlall = "select count(*) as result from user";  
	            rs = stmt.executeQuery(sqlall);  
	            while(rs.next())  
	            {  
	                 count = rs.getInt("result"); 
	            }  
				
	            tableuser= new Object[count][];
				String sql = "select * from user";
				rs = stmt.executeQuery(sql);
				int i=0;
				while (rs.next()) {
					String user = rs.getString("user");
					String pass = rs.getString("pass");
					tableuser[i]=new Object[]{user,pass};	
					i++;
				}
			} catch (Exception e) {
				e.printStackTrace();
			} finally {
				closedb();
			}
			
			return tableuser;
	}
