单个表中的条件下拉列表

Question

It is fairly simple to populate a drop-down list from a fixed table of names (here 'Name1') using data validation.

Is it possible to populate a second drop-down list from a second, unnormalised table, akin to doing a lookup on the range with the input value being the selection from the first drop-down list?

eg Selecting 'A' from the first drop-down means only 'D', 'E' and 'F' are available in the second drop-down.

Unfortunately, the second table cannot be split out into tables 'A', 'B' and 'C' as there are plenty of tutorials explaining how to do it that way.
