Solution to generate table output of data, comments and suggestions please.

I thought I'd make up pseudo rhtml/ruby code I would like to use to
create table views in html.

I basically need flexible helpers to create tables (and later lists). I
do not want to write over and over again the same stuff.

This is what I made up in about an hour. I am still new to RoR.

What do you think about this approach? Which problems do you see
theoretically, practically and implementation wise? Can you suggest
another maybe better approach?

I hope for some feedback.

(jt just stands for jonas tag, i wanted to make sure that i wont take
any actionview method name that might probably be used in future rails
versions like table_tag_start or so)

<% jt_table_begin :for => jt_create_data_from @categories,
                  :options => { :print_html_comments => false } -%>
<!-- the option in the table tag method removes any html comments from
     output -->
<!-- raw data between begins and ends is being parsed to extend given
tags by
     class / id attributes and fill values of elements/tags -->
<table cellspacing="0" cellpadding="0">
<!-- all these parameters are optional -->
<!-- jt_tr_begin adds a adds (or, like in this case, if given)
     extends a tr_tag -->
  <% jt_loop_data -%>
  <% jt_tr_begin :css_helpers => { :numerate, :first_n_last,
:odd_n_even, :id => :primary_key_id } -%>
  <tr width="100%">
    <% jt_loop_data -%>
    <!-- following is method block (jt_th_begin until jt_th_end)
"probably" result into something like this:
       <th align="center" valign="middle" class="no1 first name">
        <a href="#order_swap">Name</a>
        <a href="#order_asc">&uarr;</a>
        <a href="#order_desc">&darr;</a>
       <th align="center" valign="middle" class="no2 status">
       <th align="center" valign="middle" class="no3 updated_on">
        <a href="#order_swap">Updated on</a>
        <a href="#order_asc">&uarr;</a>
        <a href="#order_desc">&darr;</a>
       <th align="center" valign="middle" class="no4 last created_on">
        <a href="#order_swap">Created on</a>
        <a href="#order_asc">&uarr;</a>
        <a href="#order_desc">&darr;</a>
    <% jt_th_begin :colums_show => { :name, :status, :updated_on,
:created_on },
                   :colums_orderable => { :name, :updated_on, :created_on
                   :css_helpers => { :numerate, :first_n_last,
:class => :column_name }
       ) -%>
    <th align="center" valign="middle">
      <% jt_loop_data -%>
    <% jt_th_end -%>
    <% jt_td_begin :css_helpers => { :numerate, :first_n_last,
:odd_n_even } -%>
    <td valign="top">
      <% jt_loop_data -%>
    <% jt_td_end -%>
  <% jt_tr_end -%>
<% jt_table_end -%>

What do you think?
