Rails - Jan 2007 - Need help for Helper

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:
  <div class=''table_header''>Name</div>
  <div class=''table_header''>Age</div>
  <div class=''table_header''>Sex</div>

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...

Tomasz Tomczyk

Are you saying you have one _visible_ line?  Or that, when you look at the 
DOM you''ve actually got one string?  Without seeing your code, my first
guess would be that you''ve got a CSS problem, not a Rails problem.  You
might want to try the block form of content_tag, just to help separate the 
issues.

hth,
Bill

Finally I''ve found the problem - it was me :-)
There was no return clause in the helper, which caused it to print 
everything in "for" loop.

Now its OK.

Thanks anyway,
Tomasz Tomczyk
