MATLAB: How to display a table object in command window in a different color

colorcprintfdisplaytable

I am working with tables and I was wondering how to display the table in a different color. I know you can use the cprintf function for regular strings but it doesn't work if I try to pass an object table.

Ideally it should be something like this

MyTable = table (1, 2, 3)
disp(MyTable,'r')

There is no direct way. You have to create a string at first, e.g. using evalc('disp(MyTable)').

This suffers from the same problems as eval and assignin, but if you do not use this to create variables, but catch the string output only, there is a chance that it does not make your code evil.

Are you really sure that this is useful? What about the output to a specific GUI? The command window has very limited possibilities only, and squeezing them might not be useful. As soon as more sophisticated output is required, a HTML display in a GUI might be smarter at all.

You can do this with EVALC (<http://www.mathworks.com/help/matlab/ref/evalc.html>)

displaystring = evalc('display(obj)');

It does sound like varfun is indeed what you need.

For example, to multiply all your columns by 1.5

newtable = varfun(@(col) col*1.5, yourtable)

You can easily include or exclude some particular columns by filtering the strings returned by yourtable.Properties.VariableNames and passing that as 'InputVariables' to varfun if required.

You can also easily rename the columns in the new table, for example, to add 'Wt' to all the names

newtable.Porperties.VariableNames = compose('%sWt', string(newtable.Porperties.VariableNames));

In any case, I would advise against creating new variables, particularly using eval.
