Add support for fixing indentation in jinja

 {% endfor %}
 
 ```

+## Indented content like content tabs
+
+If you inserted content has multiple lines, then indentation will be not be retained beyond the first line. This means things like [content tabs](https://squidfunk.github.io/mkdocs-material/reference/content-tabs/#usage) will not work as expected.
+
+To fix that, you can use the custom _filter_ `add_indendation` (a filter add to `macros` by `table-reader` plugin). For example:
+
+=== "index.md"
+
+    ```jinja
+    {% set table_names = ["basic_table.csv","basic_table2.csv"] %}
+    {% for table_name in table_names %}
+
+    === "{{ table_name }}"
+
+        { { read_csv(table_name) | add_indentation(spaces=4) }}
+
+    {% endfor %}
+    ```
+
+=== "mkdocs.yml"
+
+    ```yaml
+    site_name: test git_table_reader site
+    use_directory_urls: true
+
+    theme:
+    name: material
+
+    plugins:
+        - search

+    markdown_extensions:
+        - pymdownx.superfences
+        - pymdownx.tabbed:
+            alternate_style: true
+    ``` 
+
+!!! note "Note the space in { {"
+
+    To avoid the tables being inserted into the code example, we replaced `{{` with `{ {`.
+    If you copy this example, make sure to fix.
