Yes. All code is available:

??"Kruskal Wallis"
methods(kruskal.test)
getAnywhere(kruskal.test.default)

If you want to extract the table, then looking at the bottom of that  
function, you see that the variables r, g,and x have been created and   
you would need to modify that code and substitute the returned table  
you desire. The table might be a bit more complicated than that  
simplistic offering since ties need to be properly accounted for if  
you intend to replicate the results "by hand".
