alignment issue in fprint

My fprintf table is not aligned

P=[65.44; 87.12; 67.46; 79.51];
words1={'Moisture';'Fixed carbon';'Volatile matter';'Ash'};words2 = repmat({'wt%'},length(P),1);
D={words1,P,words2};
for k1 = 1:size(words1,1);
    fprintf('%s \t %.2f \t %s \n',char(D{1}(k1)),D{2}(k1,:),char(D{3}(k1)))
end

excecutes as follows:

Moisture 65.44 wt%

Fixed carbon 87.12 wt%

Volatile matter 67.46 wt%

Ash 79.51 wt%

Could someone please help in figuring out how to align the strings and digits.

P=[65.44; 87.12; 67.46; 79.51];
words1={'Moisture';'Fixed carbon';'Volatile matter';'Ash'};
words2 = repmat({'wt%'},length(P),1);
D={words1,P,words2};
for k1 = 1:size(words1,1);
    fprintf('%20s \t %.2f \t %s \n',char(D{1}(k1)),D{2}(k1,:),char(D{3}(k1)))
end

            Moisture 	 65.44 	 wt% 
        Fixed carbon 	 87.12 	 wt% 
     Volatile matter 	 67.46 	 wt% 
                 Ash 	 79.51 	 wt%

Thanks very much! I think 20s is figured out through a series of trials?; I am wondering if there is a more elegant way to do it. Also, what if I had my P matrix as follows: P=[5.44; 87.12; 67.46; 9.51]; decimal places do not align...

It does, you just have to specify the total width you want:

P=[5.44; 87.12; 67.46; 9.51];
fprintf('data: %5.2f\n',P)

data:  5.44
data: 87.12
data: 67.46
data:  9.51

P=[65.44; 87.12; 67.46; 79.51];
words1={'Moisture';'Fixed carbon';'Volatile matter';'Ash'};
words2 = repmat({'wt%'},length(P),1);

T = table(words1,P,words2)

T = 4×3 table
          words1             P      words2 
    ___________________    _____    _______

    {'Moisture'       }    65.44    {'wt%'}
    {'Fixed carbon'   }    87.12    {'wt%'}
    {'Volatile matter'}    67.46    {'wt%'}
    {'Ash'            }    79.51    {'wt%'}
