Question

I’m trying to build a html table in Ruby On Rails with the help of the content_tag method.

Example:

@template.content_tag(:tr, @template.content_tag(:td, options[:argument0]))

This should render to

<tr><td>content of argument0</td></tr>

What I need is something like

<tr><td>content of argument0</td><td>argument1</td> ... </tr>

Can I build this with the same method? How can I pass two content_tags?

You can use concat :

 @template.content_tag(:tr, 
    @template.content_tag(:td, options[:argument0]).
    concat(@template.content_tag(:td, options[:argument1])).
    concat(@template.content_tag(:td, options[:argument2]))
    # ....
 )

Or using a loop – as OP suggested in the comments

rows = returning "" do |cells|
   5.times do |i|
     cells.concat @template.content_tag(:td, options["argument#{i}".to_sym]
   end
end
@template.content_tag(:tr,rows)
