Read table in .txt to MATLAB

I have the following .txt fil and wish to save the columns seperately for further polar extrapolation. However, the following code is resulting in some funny values.

I appreciate any help. I think I am reading the data wrong as I dont fully understand the concept.

Thanks in advance.

%Read data file: Drag and Lift Coeff.
saveFlCdCl = 'Save_CdCl.txt';   %File name
finputCdCl = fopen(saveFlCdCl);    %Open file for reading

dataBuffer = textscan(finputCdCl, '%f %f %f ', 'CollectOutput', 1, ...   %Read data from file
                                     'Delimiter', '', 'HeaderLines', 12);

%Get values
PolarAoA=dataBuffer{1}(:,1);
PolarCl=dataBuffer{1}(:,2);
PolarCd=dataBuffer{1}(:,3);
fclose(finputCdCl);  %Close file

%Read data file: Drag and Lift Coeff.
saveFlCdCl = 'https://www.mathworks.com/matlabcentral/answers/uploaded_files/586711/Save_CdCl.txt';   %File name
t = readtable(saveFlCdCl, 'readvariablenames', false, 'headerlines', 12);
t.Properties.VariableNames = {'alpha', 'CL', 'CD', 'CDp', 'CM', 'Top_Xtr', 'Bot_Xtr'};

t(1:5,:)

ans = 5×7 table

Needed the seperate columns but got to it in the end thanks to your answer. Much appreciated

[David Hill]

t=readtable('Save_CdCl.txt');
alpha=t.alpha;
names=t.Properties.VariableNames;
for k=1:length(names)
  writetable(t(:,k),names{k});
end
