I'm not sure exactly what you're asking.  You want the \mu and the s_j
in the top row to line up on the same baseline, the s_i and the s_j in
the bottom row to line up on the same baseline, and you want the \mu
and the s_i in the first column, and the s_j and s_j in the second column.

Plus you want a little space between the two columns, it looks like.

Weird, but I'll try my hand at it.

$\delta^{\vphantom{j}\mu}_{\vphantom{j}s_i} {}^{s_j}_{s_j}$

The key thing is to put those \vphantom{j}s in; they take up no
horizontal space, but create essentially a box the height and
depth of the formula contained in the parameter.
