 `TypedTableBlock` can be imported from the module `wagtail.contrib.typed_table_block.blocks` and used within a StreamField definition. Just like `StructBlock` and `StreamBlock`, it accepts a list of `(name, block_type)` tuples to use as child blocks:
 
 ```python
-  from wagtail.contrib.typed_table_block.blocks import TypedTableBlock
-  from wagtail.core import blocks
-  from wagtail.images.blocks import ImageChooserBlock
+from wagtail.contrib.typed_table_block.blocks import TypedTableBlock
+from wagtail.core import blocks
+from wagtail.images.blocks import ImageChooserBlock
 
-  class DemoStreamBlock(blocks.StreamBlock):
-      title = blocks.CharBlock()
-      paragraph = blocks.RichTextBlock()
-      table = TableBlock([
-          ('text', blocks.CharBlock()),
-          ('numeric', blocks.FloatBlock()),
-          ('rich_text', blocks.RichTextBlock()),
-          ('image', ImageChooserBlock())
-      ])
+class DemoStreamBlock(blocks.StreamBlock):
+    title = blocks.CharBlock()
+    paragraph = blocks.RichTextBlock()
+    table = TableBlock([
+        ('text', blocks.CharBlock()),
+        ('numeric', blocks.FloatBlock()),
+        ('rich_text', blocks.RichTextBlock()),
+        ('image', ImageChooserBlock())
+    ])
 ```
 
 To keep the UI as simple as possible for authors, it's generally recommended to use Wagtail's basic built-in block types as column types, as above. However, all custom block types and parameters are supported. For example, to define a 'country' column type consisting of a dropdown of country choices:
 
 ```python
-      table = TableBlock([
-          ('text', blocks.CharBlock()),
-          ('numeric', blocks.FloatBlock()),
-          ('rich_text', blocks.RichTextBlock()),
-          ('image', ImageChooserBlock()),
-          ('country', ChoiceBlock(choices=[
-              ('be', 'Belgium'),
-              ('fr', 'France'),
-              ('de', 'Germany'),
-              ('nl', 'Netherlands'),
-              ('pl', 'Poland'),
-              ('uk', 'United Kingdom'),
-          ])),
-      ])
+    table = TableBlock([
+        ('text', blocks.CharBlock()),
+        ('numeric', blocks.FloatBlock()),
+        ('rich_text', blocks.RichTextBlock()),
+        ('image', ImageChooserBlock()),
+        ('country', ChoiceBlock(choices=[
+            ('be', 'Belgium'),
+            ('fr', 'France'),
+            ('de', 'Germany'),
+            ('nl', 'Netherlands'),
+            ('pl', 'Poland'),
+            ('uk', 'United Kingdom'),
+        ])),
+    ])
 ```
 
 On your page template, the `{% include_block %}` tag (called on either the individual block, or the StreamField value as a whole) will render any typed table blocks as an HTML `<table>` element.
 
 ```html+django
-    {% load wagtailcore_tags %}
+{% load wagtailcore_tags %}
 
-    {% include_block page.body %}
+{% include_block page.body %}
 ```
 
 Or:
 
 ```html+django
-    {% load wagtailcore_tags %}
+{% load wagtailcore_tags %}
 
-    {% for block in page.body %}
-        {% if block.block_type == 'table' %}
-            {% include_block block %}
-        {% else %}
-            {# rendering for other block types #}
-        {% endif %}
-    {% endfor %}
+{% for block in page.body %}
+    {% if block.block_type == 'table' %}
+        {% include_block block %}
+    {% else %}
+        {# rendering for other block types #}
+    {% endif %}
+{% endfor %}
 ```
