Table Format Support

[ofou]

Currently, our application displays tables in a basic format that lacks visual clarity (as shown in the first screenshot). We should improve the table formatting to match the more readable, structured format shown in the second screenshot.

Problem

• Poor visual hierarchy
• Difficult to distinguish between rows and columns
• Less readable for complex test case information
• Suboptimal experience in architect mode

Proposed Solution

Implement enhanced table formatting that includes:

• Clear column separators
• Better row styling with alternating background colors
• Proper alignment of content within cells
• Consistent padding and spacing
• Special styling for headers
