I have a multiindex. I want to turn this:
0 0 black
1 0 brown
2 0 beige
4 0 green
5 0 gris clair
6 0 forest green
7 0 tan
8 0 burgandy
1 black
9 0 off white
10 0 silver
11 0 pink
Into this:
0 black
1 brown
2 beige
4 green
5 gris clair
6 forest green
7 tan
8 burgandy
9 black
10 off white
11 silver
12 pink
Not much more to say, though SO says I have written too much code in this post so here I am typing more words.
