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.

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

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%'}
