[Bug] Data Grid Component - Dynamic column width does not work

Data Grid Component - Dynamic column width does not work

## Summary
The dynamic input field for the width of any Data Grid Component field does not accept a value. It only works for hard coded values.

## Steps to Reproduce
1. Create a field say in the users table so it is accessible anywhere
2. In the data grid component, set the width dynamically to that field.
3. The value is ignored

## Current Behavior
The value is ignored

## Expected Behavior
The column width should change as per the value in the column chosen. Useful for hiding columns.
