Just saw this other thread asking pretty much the same question
Way to concatenate tables with some but not all variables in common?

I am trying to concatenate several similar tables that have mostly the same variables, but a few differences. In the cases of different variables I'd want to pad values with NaN.
For example:
A =
var1 var2
____ ____
1 2
B =
var1 var3
____ ____
1 3
C=somefunction(A,B)
C =
var1 var2 var3
____ ____ ____
1 2 NaN
1 NaN 3
Is there any canned function that does this?

Gabe, hacking outerjoin to do vertical concatenation is super clever, but I think it isn't going to work for you, because the common variables that you'd use as the "key" (Var1 in your example) have values in common. At least in your example they do.
I think you'd be safer just finding the setxor of the two lists of var names, and creating the vars you need using NaNs.

Here is a "canned" FEX function (tblvertcat) I just refactored using some old code I wrote a while ago and based on a MATLAB Answers post. It can be used for an arbitrary number of tables, and supports double, char, cell, struct, etc.
