下文笔者讲述guava中Table集合的简介说明，如下所示

guava之Table集合简介

Table集合: 
   用于存储数据表，类似于Map<String,Map<String,String>>这种结构
   Table集合实现了指定接口
       ArrayTable, ForwardingTable, 
	   HashBasedTable, ImmutableTable,
       TreeBasedTable

例:

 public static void main(String[] args) {
        Table<String,String,String> table= HashBasedTable.create();
        table.put("keyIdA","类型111","备注111");
        table.put("keyIdB","类型222","备注222");
        table.put("keyIdC","类型333","备注333");

	    System.out.println(table.columnKeySet());
        System.out.println(table.cellSet());
        System.out.println(table.rowKeySet());
        System.out.println(table.values());
        System.out.println(table.rowMap());
        System.out.println(table.columnMap());
    }
