Would like to implement a grid, which expands/collapses horizontally i.e. if there are 20 columns, in first look, grid will display 10 columns, upon clicking on expand button, the next 10 rows needs to be displayed.

Any other suggestion on implementation would be nice, like scrolling and dynamic loading.
