both return 2 because the reference only contains column B as the second column in the table. Because single-column areas have only one column number, it does not make a difference whether or not the formula is used as an array formula.
都返回 2，因为引用仅包含在表格中作为第二列的 B 列。由于单列区域仅有一个列编号，所以公式是否作为数组公式使用对结果没有影响。
