Patent Title: Web browser column control

Assignee: IBM
Patent Number: US6232967
Issue Date: 05-15-2001

Abstract: Web browser interaction with HTML files is modified to allow for columns of row headings to be defined as non-scrollable so that the headings will always be visible as the data rows are scrolled to the left or to the right. Multiple non-scrollable row headings may be in an adjacent position and certain row headings are allowed to displace other columns of row headings when they are in an adjacent position. A new HTML tag, referred to as the column scroll tag, identifies a column of row headings in a file as non-scrollable depending on the screen position of the column. When there is a column of headings that reach the left-most position of the screen, the columns become locked and remain on the screen. A column scroll tag also has the property of displacement or no displacement. Displacement means that once two non-scrollable columns are adjacent, the right-most non-scrollable column would immediately displace the left-most column non-scrollable column, when the data is scrolled to the left on a screen. When the data is scrolled to the right on a screen, displacement means that once two non-scrollable columns are adjacent, the left-most non-scrollable column would immediately displace the right-most column non-scrollable column, when the data is scrolled to the left on a screen. Non-displacement means that when two columns are adjacent and at the left-most or right-most column positions, they both become locked in such screen positions.
