Probability table layout ambigious

[Former user]

If a node B has only one parent A, the edit probability dialog shows

A present absent present absent

It is not clear if A refers to the rows or to the columns. There should be a visual clue.

[Francisco Javier Díez]

It can be fixed by coloring all the cells in a header row in the same color. For example, in the attached figure there might be a color for C and another color for A.

Another issue about the table shown in this figure is that the same values for the same variable should have the same color. For example, one color for C=absent and another one for C=present.
