Increase RSE prefix column width for full visibility

[maany]

Description

The prefix column in RSE tables is currently too narrow, causing content to be truncated. This reduces readability and forces users to hover or interact to see full values. The column width should be increased to ensure full visibility of prefix content.

Current Behavior

• Prefix column has limited width
• Content gets truncated with ellipsis
• Users cannot see full prefix values at a glance

Proposed Solution

• Increase the default width of the prefix column
• Ensure content is fully visible without truncation
• Maintain responsive design for different screen sizes

Implementation Details

1. Analyze typical prefix content length
2. Adjust column width CSS/styling
3. Ensure table layout remains balanced
4. Test on various screen sizes
5. Consider making column width adjustable by users

Acceptance Criteria

• Prefix column displays full content without truncation
• Column width is appropriate for typical prefix values
• Table layout remains visually balanced
• Responsive behavior works on mobile and desktop
• No horizontal scrolling introduced unnecessarily
