By default the table displays:
Total number of products imported from Merchant Center

Product SKU based on SKU Mapping from Google Analytics
Name (Product Title) based on your feed

Price, Cost, Margin - Price is derived from your feed while Cost and Margin are built off of either your default settings or when the Margin Tool is utilized.
You may also edit/adjust the table and displayed information using the 3-bar menu as seen in the upper right corner in the image above.
