module Trestle
module TableHelper
# Renders an existing named table or builds and renders a custom table if a block is provided.
#
# name - The (optional) name of the table to render (as a Symbol), or the actual Trestle::Table instance itself.
# options - Hash of options that will be passed to the table builder (default: {}):
# :collection - The collection that should be rendered within the table. It should be an
# Array-like object, but will most likely be an ActiveRecord scope. It can
# also be a callable object (i.e. a Proc) in which case the result of calling
# the block will be used as the collection.
# See Trestle::Table::Builder for additional options.
# block - An optional block that is passed to Trestle::Table::Builder to define a custom table.
# One of either the name or block must be provided, but not both.
#
# Examples
#
# <%= table collection: -> { Account.all }, admin: :accounts do %>
# <% column(:name) %>
# <% column(:balance) { |account| account.balance.format } %>
# <% column(:created_at, align: :center)
# <% end %>
#
# <%= table :accounts %>
#
# Returns the HTML representation of the table as a HTML-safe String.
