def pagination(collection:, entry_name: nil, **options)
  collection = collection.call if collection.respond_to?(:call)
  render "trestle/table/pagination", collection: collection, entry_name: entry_name, options: options
end

#table(name = nil, options = {}, &block) ⇒ Object

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.
