+Feature: TableRow liquid tags
+  As a designer
+  I want to be able to use the tablerow liquid tag with locomotive contents
+
+Background:
+  Given I have the site: "test site" set up
+  And I have a custom model named "Projects" with
+    | label         | kind      | required  |
+    | Name          | string    | true      |
+  And I have entries for "Projects" with
+    | name        |
+    | Project 1   |
+    | Project 2   |
+    | Project 3   |
+
+Scenario: Use the tablerow tag
+  Given a page named "project-table" with the template:
+    """
+    <h1>Projects</h1>
+    <table>
+    {% tablerow project in contents.projects cols: 2 %}
+    {{ project.name }}
+    {% endtablerow %}
+    </table>
+    """
+  When I view the rendered page at "/project-table"
+  Then the rendered output should look like:
+    """
+    <h1>Projects</h1>
+    <table>
+    <tr class="row1">
+    <td class="col1">
+    Project 1
+    </td><td class="col2">
+    Project 2
+    </td></tr>
+    <tr class="row2"><td class="col1">
+    Project 3
+    </td></tr>
+
+    </table>
+    """
