I need a helper, which will render a table in my customized style.  
I wrote a code like this:

template.rhtml:  
\<% @column\_names = [“Name”, “Age”, “Sex”] %\>  
\<%= table\_show @column\_name %\>

helper.rb  
def table\_show(names)  
for name in names  
content\_tag ( :div, name, :class =\> ‘table\_header’ )  
end  
end

Which should give me an output like this:

Name

Age

Sex

Unfortunately I have only one line of output which looks like:  
NameAgeSex

After few trials it seems, that this output is being generated by line:  
“for name in names”, because deleting “content\_tag…” doesn’t make any  
differences.

What am I doing wrong?  
I suppose that helper def does treat an Array like a String…

You will probably get a better response if you ask this on the Ruby on  
Rails mailing list. The Ruby-talk mailing list (and forum, and  
comp.lang.ruby newsgroup) is primarily for discussion of the Ruby  
language itself, not the Ruby on Rails web framework that happens to  
use it.
