倒排映射和压缩数组等其他一些数据结构也具有类似的优点；参考资料一节中Gillam的书中有关于这些数据结构更详细的资料。

There are other structures such as inversion maps and compact arrays that also merit a closer look; see the Gillam book in the Resources section for more information on those.

它使用了一个函数(此段代码中的cellfuncs)数组，其中的每个函数都用来压缩或转换数据，以便将数据放入表的单元格内。

It USES an array of functions (cellfuncs in the code) where each function is used to extract and transform the data so it can be put into a table cell.

大多数情况下，这种情况不会发生，哈希函数需要把较大的关键字值范围压缩成较小的数组下标的范围。

In most cases neither of these situations exist, and the hash function will need to compress a larger range of keys into a smaller range of index Numbers.
