This PR address the scrollbar width on schedule page when the page is accessed on Microsoft edge and Firefox browsers. Initially both horizontal and vertical scrollbars appeared on sessionblocks on schedule page table, so to remove it, i've adjusted the sessionblock min width to remove horizontal scrollbar and did shrunk vertical scrollbar.
