问题
我有一个数字列表，位于 A 列的不同行号对应的 B 列（例如，在 B1，我有列表 {1,2,3}）。
我想把这个列表转换为单元格列表（{A1,A2,A3}），并在 C 列应用一个公式（例如，我想要对它们进行 AND 运算）。
A 列始终包含布尔值。
B 列始终包含由逗号分隔的有效行号。
我想要一个可以放在 C 列并向下拖动以提取数字的公式（例如使用 =SPLIT(B1,",")），然后对其应用公式。
下表显示了我想要实现的示例。请注意，C 列包含了手动输入方法，我希望避免使用。
| 列 A | 列 B | 列 C | 列 D（期望输出）
| -------- | ------ | -------------- | -----------
行 1 | TRUE | 1,2,3 | =AND(A1,A2,A3) | FALSE
行 2 | FALSE | 2,4 | | FALSE
行 3 | FALSE | 4,6,2,1| | FALSE
行 4 | FALSE | 2 | | FALSE
行 5 | TRUE | 1,5 | | TRUE
行 6 | FALSE | 1,5,3 | | FALSE
一些我尝试过的方法包括使用：
=INDEX(A:A, SPLIT(B1,","), 1)
=AND(ARRAYFORMULA(INDEX(A:A, SPLIT(B1,","), 1)))
我还尝试过改变上述方程中的公式顺序，但都无济于事。
我只成功让我的公式受到 B 列中第一个行号的影响。
英文:
I have a list of numbers in Column B corresponding to different rownumbers in Column A (for example, in B1, I have the list {1,2,3}).
I would like to turn this list into a list of cells ({A1,A2,A3}) and apply a formula to that list in Column C (for example, I would like to AND them together).
Column A always contains Boolean Values.
Column B will always contain valid rownumbers separated by a comma.
I would like a formula that I can put in Column C and drag down and extract the numbers from (for example using =SPLIT(B1,",")) and then apply a formula to.
Shown in the table below is a sample of what I would like to achieve. Note that Column C contains a manual entry approach that I would like to avoid.
| Column A | Column B | Column C | Column D (expected ouput)
| -------- | -------- | -------------- | -----------
Row 1 | TRUE | 1,2,3 | =AND(A1,A2,A3) | FALSE
Row 2 | FALSE | 2,4 | | FALSE
Row 3 | FALSE | 4,6,2,1 | | FALSE
Row 4 | FALSE | 2 | | FALSE
Row 5 | TRUE | 1,5 | | TRUE
Row 6 | FALSE | 1,5,3 | | FALSE
Some things I have tried include using
=INDEX(A:A,SPLIT(B1,","),1)
=AND(ARRAYFORMULA(INDEX(A:A,SPLIT(B1,","),1)))
I have also tried moving around the order of the formulas in the above equation to no avail.
I have only managed to get my formula to be affected by the first rownumber in column B.

你很接近了！使用 BYCOL（考虑到 SPLIT 结果是一系列列中的单元格），你可以获取 A 列的 INDEX；并将其包裹在 AND 函数中：
=AND(BYCOL(SPLIT(B1,";"),LAMBDA(i,INDEX(A:A,i))))
如果你想的话，可以使用 BYROW 将其包裹，以应用到你的整个范围：
=BYROW(B:B,LAMBDA(b,IF(b="","",AND(BYCOL(SPLIT(b,";"),LAMBDA(i,INDEX(A:A,i)))))))
英文:
You were very close! With BYCOL (considering that the SPLIT result is a serie of cells in columns) you can get the INDEX of column A; and wrap it in AND:
=AND(BYCOL(SPLIT(B1,","),LAMBDA(i,INDEX(A:A,i))
If you want, you can wrap it in BYROW to apply to your whole range:
=BYROW(B:B,LAMBDA(b,IF(b="","",AND(BYCOL(SPLIT(b,","),LAMBDA(i,INDEX(A:A,i)))))))
