Your changes look good. However, try these things to adjust space allocation to prioritize widening the title column, which holds crucial information in the row, other columns are secondary and can be truncated / hidden.

• Reducing the width of the checkbox column. There is some white space next to checkboxes.
• Displaying only the icon of raw data/data product alongside the title in a tooltip, thereby making the type column narrower.

@deepakduggirala I have reduced the width of the checkbox column.

Regarding having only the icons of Raw Data/Data Product in the Type column, I don't think that just the icons would provide enough info regarding the type.

I have further increased the number of visible characters in the Name column to 25.
