One Way:

You can use diary function to save the all command window file in text form, later do the PDF conversion

diary on
% Your Code
diary off

(UPDATE: I solved this problem in a 2nd answer below)

This does not preserve formatting so it will produce very ugly results (not fitting the word "publish" in the question). Example:

diary('diary_file')
diary on
a=[1;0];
b=[0;1];
test_table=table(a,b)
diary off

The content of command window looks nice:

However the "diary_file" is awful:

I have yet to find a program (other than matlab) that can display this properly formatted. A tedious work around is to manually display it in the command window and print to pdf. Unfortunately matlab does a poor job of handling line breaks. So if you don't want to wrap lines you have to adjust the font size to avoid cutting off long lines. A user-friendly program allows you to "reduce to printer margins" so that you can avoid laboriously tweaking font settings.

I found a solution that not only preserves formatting it may allow programatic printing of the command window contents by use of a FEX file: "Print with Internet Explorer".

The .m file below works on small scale testing with tables featuring uneven headings. It basically just makes an html file out of the diary file.

Three notes: 1) HTML does not like whitespace characters so I use "&nbsp" which is not ideal. 2) I set the font to monospace without a CSS header, that also may not be ideal. 3) to print the html file to PDF or to paper carefully read Jan's comments and answer here: https://www.mathworks.com/matlabcentral/answers/376787-how-to-print-a-web-page-automatically

diary('diary_file.txt')
diary on
% NOTE: replace the next 4 lines (not including "diary off") with your own code
a=[1;0];
bbbbb=[0;rand];
% example of persnickety command window formatting
test_table=table({'var1';'var2_extra'},a,bbbbb)
diary off
%% NOTE: ALL the following lines could be in a separate file
% open the file to get the content as a string
fid  = fopen('diary_file.txt','r');
f=fread(fid,'*char')';
fclose(fid);
% adapt to html 
f=strrep(f,'\','\\',); % thanks to mahoromax's comment (accomodates windows file paths)
f=strrep(f,newline,'<br>');
f=strrep(f,' ','&nbsp');
f=['<p style = "font-family:monospace" >',newline,f,newline,'</p>'];
% write the file and view it
fid=fopen('diary_file.html','w');
fprintf(fid,f);
fclose(fid);
winopen('diary_file.html') % windows only?
