Color functionality to the code.

[jlmolinero]

The user only need to add color substring to the text in cell, with a bash format.

Examples and guide:

Thanks for the PR. I like the idea of adding color support.
However, I am not a fan that the user will have to manually enter the ansii escape sequences (It is easy to mess that up e.g. forget the reset escape sequence etc).
Instead, I would prefer an abstraction, where the user can just call function that colors a specific cell/row/col.
Something like:

table.set_cell_background_color(x, y, color);
table.set_cell_text_color(x, y, color);

Where color could be an enum of the 256 pre-defined colors, - they have names.
That way we could have a pre-defined mapping between ansii-color-sequences to an identifier a human can understand.

Maybe it would also make sense to have something like an init_colors() function that needs to be called at the start, to verify if 256 colors is supported by the terminal, otherwise, fallback to 16 colors.
Let me know if you are interested in making these changes.

Hello, sorry for the delay in responding but I have been a father and I have not been able to dedicate myself to this outside of work, now that the girl is older I have a little more time...

I will try to do something about it, I also wanted to tell you that I am going to use your code with some modifications for a Linux command that I am preparing, it is like a "free" linux command but on steroids.

I'm still in a very early version.

Greetings, I hope to give you information and modifications in a short period of time...

I hope my daughter lets me work.

@jlmolinero No problem, I will leave the issue open and you can get back to me if you made some progress. 👍

While this is a fairly old project of mine, I would still like to keep the API pretty self-descriptive and simple.
So it would be nice to have explicit functions to change the color as stated in my previous reply.
