类名称：Table
方法名：column

Table.column介绍

[英]Returns a view of all mappings that have the given column key. For each row key / column key / value mapping in the table with that column key, the returned map associates the row key with the value. If no mappings in the table have the provided column key, an empty map is returned.

Changes to the returned map will update the underlying table, and vice versa.
[中]返回具有给定列键的所有映射的视图。对于表中具有该列键的每个行键/列键/值映射，返回的映射将行键与值相关联。如果表中没有映射具有提供的列键，则返回空映射。
对返回映射的更改将更新基础表，反之亦然。
