Abstract:
Displaying tabular information in a user interface (UI) on a display screen is enhanced by freezing selected non-adjacent columns (rows). Freezing ensures the display of the selected non-adjacent columns (rows) when scrolling to bring other columns (rows) into the table for display. Border rows (columns) may also be frozen when scrolling. A table in a document navigable by moving a focus to scroll the document may be displayed by a UI control configured to automatically display the frozen border rows (columns). When scrolling a focus in the document at an edge of the display screen to bring the UI control into the display, the UI control aligns a portion of the table with the edge and paints the frozen border row (column). The UI control maintain the display of the border row (column) when scrolling through the table.
