Add frozen columns and row hover highlight to data table

[mdrxy]

When horizontally scrolling through the data table, it's difficult to track which provider/model a row belongs to since the identifying columns scroll out of view. Additionally, with many rows visible, it's easy to lose track of which row you're looking at.

I'd propose:

1. Frozen (sticky) columns

• Allow the Provider and Model columns to remain fixed on the left while scrolling horizontally
• Options:
  • Always freeze these columns by default
  • Add a toggle/setting to freeze specific columns
  • Right-click context menu on column header to "Freeze column"

2. Row hover highlight

• Highlight the entire row on mouse hover to improve visual tracking across wide tables

Use Case

When comparing metrics across many columns, I need to scroll horizontally while still seeing which provider/model I'm looking at. The frozen columns act as primary key references. Row highlighting helps when scanning data in dense tables, like this one.
