data1:

    meta  particle  ratio   area    type     0   2     part10    1.348   0.8365  touching 1   2     part18    1.558   0.8244  single   2   2     part2     1.893   0.894   single   3   2     part37    0.6695  1.005   single   ....clip... 36  2     part23    1.051   0.8781  single   37  2     part3     80.54   0.9714  nuclei   38  2     part34    1.071   0.9337  single

data2:

    meta  particle  ratio    area    type     0   3     part10    0.4756   1.025   single   1   3     part18    0.04387  1.232   dusts    2   3     part2     1.132    0.8927  single   ...clip... 46  3     part46    13.71    1.001   nuclei   47  3     part3     0.7439   0.9038  single   48  3     part34    0.4349   0.9956  single

the first column index

the append function has optional argument ignore_index should use here join records together, since index isn't meaningful application.
