I am trying to increase the width of a column in a modern SP list. Here is an image prior to adding JSON:

enter image description here

As you can see, the width of the "Description" column needs to increase in order to show the content. So I added this JSON in Column Formatting:

This script works to adjust the column width, but it messed up the content:

I'm not sure why this script changed the entries in the description column. Any help here would be great.

Multi-Line Text column with enhanced rich text are not fully supported using JSON formatting in SharePoint.

Microsoft Documentation: JSON formatting - Supported column types

Update from comments:

To increase the width of column, try this:

  1. Go to SharePoint list. In my list, "Message Body" is a Multi-line text with enhanced rich text column:

    enter image description here

  2. Select the right edge of column header, drag to the right & increase the width like:

    enter image description here

  3. It will look like below image. Also, it will change the current list view & show the * in view name:

    enter image description here

  4. Click on the view name from Switch view options dropdown (highlighted in yellow in above image) & select Save view as.

  5. It will open a popup like below. Just click on Save without changing anything:

  • Thank you for the response. Is there another way I can either expand the width of the column or wrap the text if I'm using Multi-line text with enhanced rich text?
