知豆号数据库列（column）是什么概念啊？
最近隐隐觉得 hbase 的 “column oriented” 跟 “列式数据库” 中的含义似乎有点区别：
hbase 语境中的列是数据的一个
维度
，可以动态增长列的数量，而列数据的磁盘组织仍与 row store 无异，相邻的行数据有存储局部性。
而 “column store” 相对于 “row store” 在磁盘布局方面的差异更为本质，每一列都独立相邻存储，便于对列内同质的数据做批量操作。
不过 hbase 里面 column family 的概念更接近 column store 中的列。
COLUMN函数是什么意思？
COLUMN函数是一种Excel函数，用于返回指定单元格的列号。该函数的参数为单元格的引用，可以是单元格地址、单元格名称或包含单元格地址、名称的其他公式/函数。返回值为整数类型，表示指定单元格所在的列的编号，从1开始计算。COLUMN函数可以与其他函数一起使用，例如可以在索引函数中用于指定列参数。它是Excel中非常常用的函数之一，可以方便地进行数据分析和运算。
