 From the help about the align argument:

Character vector of length equal to the number of columns of the 
resulting table, indicating the alignment of the corresponding columns. 
Also, "|" may be used to produce vertical lines between columns in LaTeX 
tables, but these are effectively ignored when considering the required 
length of the supplied vector. If a character vector of length one is 
supplied, it is split as strsplit(align, "")[[1]] before processing. 
Since the row names are printed in the first column, the length of align 
is one greater than ncol(x) if x is a data.frame. Use "l", "r", and "c" 
to denote left, right, and center alignment, respectively. Use "p{3cm}" 
etc. for a LaTeX column of the specified width. For HTML output the "p" 
alignment is interpreted as "l", ignoring the width request. Default 
depends on the class of x.
