+### Specifying max text length in the column
+
+If you want to restrict max number of characters displayed in the column you can use `truncated` param together with `maxTextLength`.
+
+Example of using `truncated` from a JSON config file:
+
+```json
+[
+ {"type": "text", "key": "id", "title": "Id"},
+ {"type": "text", "key": "name", "title": "name", "truncated": true, "maxTextLength": 100},
+]
+```
+
+HTML `<data-column>` element example:
+
+```html
+...
+    <data-columns>
+        <data-column [truncated]="true" [maxTextLength]="100" key="name" title="Name"></data-column>
+        ...
+    </data-columns>
+...
+```
