：Tableau Excel 插件扩展
由于
Tableau
的开发宗旨一直是让用户处于分析的流程中——而不是让他们不断地
搬出
Tableau
来完成任务，因此开发人员在核心工具
Tableau Desktop
中内置了更多
的数据准备功能。这样做的问题是，所有的数据准备工作都发生在数据连接窗口中，

可能更容易。然而，
并不是所有的事情都有一个直接的答案，所以我们将介绍一些需要考虑的因素。在

Tableau Prep

Desktop
中保留连接可以让你随时改变连接类
型和条件。增加了连接计算后，就可以直接在
Desktop
中处理大多数需要从其他数
据源添加数据列的情况。如果你对数据不熟悉，或者不确定连接的结果，我建议改
用
Prep Builder
。
