#Data List is built on Salesforce's Lightning Datatable, and defaults to fixed column width mode—each column shares equal width across the available viewport.

• On Windows: Simply drag a column edge to increase its width. Once the total width exceeds the viewport, horizontal scrolling is enabled automatically.
• On macOS: A user must set Show scroll bars to Always in System Preferences in order to enable horizontal scrolling when columns are resized.

For more predictable behavior, set Q: Column Widths Mode to Auto and define a Q: Min Column Width. This allows columns to size naturally based on their content and enables scrolling when needed.
