Whoa there nellie. Complexity ahoy.

Why would you want to have a view that dumps out its HTML as a string? If a string of HTML is all you want, don't use a view, just use a template.

But putting that aside for a second ... for this particular example, how about this:

    render: ->
      this.$el.html JST["table_view_template"]()
      tbody = this.$el('tbody')
      for person in this.collection.models
        view = new TableRowView model: person
        tbody.append view.render().el

... or if you were in earnest about only needing the raw HTML from the sub-view, how about just rendering the row templates within the table template, making your render function as simple as this:

    render: ->
      this.$el.html this.template people: this.collection
