DataTable

A flexible DataTable component for LiveView.

Source code for the screenshot above. You get all of this in ~50loc.

Some of the features the component has:

• Filtering
• Sorting
• Expandable rows
• Pagination
• Row selection with customizable bulk actions
• Data is fetched from DataTable.Source behaviour, usable with custom data sources
• First class Ecto Source
• Support for persisting sort/filter state to query string (R)
• Tailwind theme included, but fully customizable

Rows marked with R are currently undergoing a refactor, and are rough around the edges.

def render(assigns) do
  ~H"""
  <DataTable.live_data_table
    id="table"
    source={{DataTable.Ecto, {MyApp.Repo, @source_query}}}>

    <:col :let={row} name="Id" fields={[:id]} sort_field={:id}>
      <%= row.id %>
    </:col>

    <:col :let={row} name="Name" fields={[:first_name, :last_name]}>
      <%= row.first_name <> " " <> row.last_name %>
    </:col>

  </DataTable.live_data_table>
  """
end

def mount(_params, _session, socket) do
  query = DataTable.Ecto.Query.from(
    user in MyApp.User,
    columns: %{
      id: user.id,
      first_name: user.first_name,
      last_name: user.last_name
    },
    key: :id
  )

  socket = assign(socket, :source_query, query)

  [...]
end

Installation

If available in Hex, the package can be installed by adding data_table to your list of dependencies in mix.exs:

def deps do
  [
    {:data_table, "~> 0.1.0"}
  ]
end

Tailwind Theme

If using the Tailwind theme, you must have tailwind set up for your app. You must also:

• Configure tailwind to generate styles for the data_table dependency
• Include the petal_components css in your app

Add this to the content list in your assets/tailwind.js:

"../deps/petal_components/**/*.*ex",
"../deps/data_table/**/*.*ex"

Add this to the end of your assets/css/base.css:

@import "../../deps/petal_components/assets/default.css";
