Hello,
I previously needed help transposing data which helped, however, now that I have correctly transposed, I need to merge the 3 outputs to one in what I thought was a union, however, it's not right. I have this as my set:

The output, as you can surmise is stacked, I need it horizontally like this:
| Supplier | Column A | Column B | Column C |
| Supplier A | Is Small | X | I |
| Supplier A | Is Little | X | I |
| Supplier B | Is Large | Y | J |
| Supplier B | Is Medium | Y | J |
| Supplier C | Is Medium | Z | K |
| Supplier C | Is Tiny | Z | K |
| Supplier D | Is Small | A | L |
| Supplier D | Is Large | A | L |
| Supplier D | Is Medium | A | M |
