How to import data with titles and plot on a plane ?

I am not exactly certain what you want. One way of plotting them in 3D and also projecting them on a plane is to combine a stem3 plot and a scatter3 plot —

Uz = unzip('data.zip');
% fc = fileread(Uz{1})
fidi = fopen(Uz{1},'rt');
k = 1;
while ~feof(fidi) & (k<=10)
    rl{k,:} = fgetl(fidi);
    k = k+1;
end
fclose(fidi);
VN = strsplit(rl{4}, ' ');
droplets = readtable(Uz{1}, 'FileType','text', 'HeaderLines',5);
droplets.Properties.VariableNames = VN(2:end-1)

droplets = 4670×20 table
