However, I can only make single columns.
Why, because you don't know how to make a multi column combo with a value list? Because you're not allowed to?
If the former, maybe it would entirely change your approach?
You should elaborate on the purpose and goal as the information is somewhat vague. The image looks a bit fuzzy when I enlarge it, so it's hard to say for sure, but that seems to be a lot of dis-similar information that you're trying to put in one table.
The short answer to
How can I create a column that allows for a checkbox, another column that is a drop down list, and a third that is a combo list in the same table?
is that a field for each control has to exist in the table and be bound to it.
EDIT: thank you alansidman - wish I had seen that first.
