Align inline tikz nodes text with current line text (in table)

Question

I have this table, where the first column has inline tikz nodes. I would like the text of the nodes to be vertically aligned with the text of the table.

I found this question about his (among others), the problem is that I can't use baseline=(v1.base) to aline v1, because v1 does not know itself before being shown.

(I'm using pgfplotstable, but I don't think that changes anything)
