+### Render CSV as table
+
+You can use write csv in the codeblock:
+
+~~~md
+```csvpreview {header="true"}
+firstName,lastName,email,phoneNumber
+John,Doe,[email protected],0123456789
+Jane,Doe,[email protected],9876543210
+James,Bond,[email protected],0612345678
+```
+~~~
+
+which rendered to:
+
+```csvpreview {header="true"}
+firstName,lastName,email,phoneNumber
+John,Doe,[email protected],0123456789
+Jane,Doe,[email protected],9876543210
+James,Bond,[email protected],0612345678
+```
+
+We use [Papa Parse](https://www.papaparse.com/) for parsing csv. The parsing option is given in braces: `{}`, and multiple options are seperated by a space. e.g. `{header="true" delimiter="."}`. Please read [their documentation](https://www.papaparse.com/docs#config) as reference.
