How can I horizontally align rows in fancyhdr?

Question

How can I left-align the [multiple-row] text in the right portion of my header using fancyhdr? I have something like this

\rhead{row 1\\row 2\\row 3}

where the rows aren't the same length, and I wish for them to be aligned on the left.

Answer 1

You could use \parbox in the argument of \rhead. For example:

\rhead{\parbox{5cm}{row 1\\row 2\\row 3}}

If you would like to align the widest row to the right margin, you could use \settowidth together with a length macro and use it for the parbox width. Or have a look at the eqparbox package for auto-sizing parboxes in general.
