I want to represent tabular data in Contentful. However, they don’t have an appropriate content type that handles that. For example, I want to express CO2 emissions (in gigaton) per year:

Year Emissions (in gigatons)
2010 33.1
2011 34.4
2012 35
2013 35.3
• My initial approach is to create a generic Content Model with Year (Integer) and Value (Number) as fields, then establish a link between my main model and the generic one. However, if you have ten years, then you generate 10 + 1 entries— very inefficient if you have limited entries.

• My second approach is to use a JSON Object for representing tables. It fits my use-case properly and it seems to be the appropriate data structure. However, I don’t want my users to edit JSON objects directly! It’s bad (and weird) UX!

## What worked

Solution: Use a JSON object as the underlying data structure, but represent it as a Table using a Contentful UI Extension. You get both the efficiency of JSON, with the ease-of-use of a table.

The repo contentful-labs/ui-editable-table is a nice UI extension from Contentful Labs that enables JSON Objects to be represented as a Table. If your use-case is simple (using only the master environment, static number of rows and columns, etc.), then the README instructions should work as-is. However, I did some modifications of my own:

• I updated the command-line utility it uses under the hood. The current repo uses an older and deprecated version of the Contentful CLI. This version only uploads to the master environment, and there’s no parameter to change that. In my repo, I used the modern Contentful CLI with more options and parameters.

• I merged @dmcb’s Pull Request that adds controls for altering table dimensions. The original repo has a static number of rows and columns, depending on how you set it up. The said PR fixes this and adds more user-control in the UI.

• I cleaned-up the extension name and title. It seems that the extension was an artifact from another project. I removed some unnecessary words and ensured that naming is consistent.

You can check my fork and use it for your own. There are already plans of archiving the original repo so better to try out the forks.

### Other options

• You can also try AnalogMemory’s fork. It does something similar but uses the older Contentful CLI version. If you’re just going to create UI extensions in the default master environment, then I recommend using this repo.

• There is also this cool Table extension from PDQ. You can host it yourself or just add https://pdq.github.io/contentful-table/ in your extension’s src field. The UI looks clean with options to add or remove columns and rows. I recommend checking this out.

## Conclusion

It works! At first I thought it would be alot of trouble installing an extension, but Contentful has made it easy to do so. Hopefully we can add it to this list of official extensions so that everything becomes way easier.
