I need to add a background-color to each row (tr) according to a condition, was looking at the documentation met "Backgrid.Row.extend" what you can do, just that I need to create a base template .. that would replicate in each row (tr), just that I also have some columns costumizo as the code shows. My question is .. You can add an event to listen to each line and I can only change its attributes without disrupting the structure (html)?

Every Row or Cell instance will have access to the entire model. You can access them from within your render method and add your CSS classes there. Something like this will do:

var MyRow = Backgrid.Row.extend({
  render: function () {
    MyRow.__super__.render.apply(this, arguments);
    if (this.model.get("someAttribute")) {
      this.el.classList.add("aClass");
    }
    return this;
  }
});

A row is a row, they are all the same. No need to use a template.
