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.

Claims

1. A method of displaying tabular information in a user interface on a display screen, said method comprising:

freezing the display of selected non-adjacent columns and/or selected non-adjacent rows of a table displayed in the user interface when scrolling the table.

2. The method of claim 1 further comprising:

providing a user option to freeze the display of selected columns including non-adjacent columns and/or selected rows including non-adjacent rows; and

receiving first user input selecting at least one row or column for freezing.

3. The method of claim 2 further comprising:

receiving second user input to scroll the display of the table; and

ensuring the display of the selected at least one row or column when scrolling the display of the table.

4. The method of claim 3 wherein the step of ensuring comprises:

determining additional columns and/or rows to paint with the columns and/or rows selected for freezing; and

displaying the additional columns and/or rows and the columns and/or rows selected for freezing.

5. The method of claim 1 comprising freezing a border row and/or border column of the table when scrolling the display of the table.

6. The method of claim 5 wherein the table comprises a portion of a document being displayed on the display screen, which document is navigable by moving a focus to scroll the document;

and wherein the display of the table is invoked when scrolling to bring a UI control for the table onto the display screen.

7. The method of claim 6 comprising, receiving first user input scrolling the UI control on to the display at an edge of the display screen, aligning a respective edge portion of the table to be scrolled onto the display with the edge of the display screen and painting the border row and/or border column.

8. A system for displaying tabular information in a user interface on a display screen, said system comprising:

a display screen; and

a processor and a memory coupled thereto, said memory storing instructions and data for configuring the execution of the processor to;

freeze the display of selected non-adjacent columns and/or selected non-adjacent rows of the table when scrolling the table.

9. The system of claim 8 further comprising one or more input devices for receiving user input and wherein the instructions and data configure the execution of the processor to:

provide a user option to freeze the display of selected columns including non-adjacent columns and/or selected rows including non-adjacent rows; and

receive first user input selecting at least one row or column for freezing.

10. The system of claim 9 wherein the instructions and data configure the execution of the processor to:

receive second user input to scroll the display of the table; and

ensure the display of the selected at least one row or column when scrolling the display of the table.

11. The system of claim 10 wherein the instructions and data configure the execution of the processor to:

determine additional columns and/or rows to paint with the columns and/or rows selected for freezing; and

display the additional columns and/or rows and the columns and/or rows selected for freezing.

12. The system of claim 8 wherein the instructions and data configure the execution of the processor to freeze a border row and/or border column of the table when scrolling the display of the table.

13. The system of claim 12 wherein the instructions and data define a UI control for displaying a table as a portion of a document being displayed on the display screen, which document is navigable by moving a focus to scroll the document and wherein the display of the table is invoked by scrolling to bring the UI control onto the display screen.

14. The system of claim 13 wherein the instructions and data configure the execution of the processor to:

receive first user input scrolling the UI control on to the display at an edge of the display screen, aligning a respective edge portion of the table to be scrolled onto the display with the edge of the display screen; and

paint the border row and/or border column.

15. A computer program product having computer readable code embodied therein, for execution by a processor for configuring a computer to display tabular information in a user interface on a display screen, said computer program product comprising instructions and data for configuring a processor of the computer system to:

freeze the display of selected non-adjacent columns and/or selected non-adjacent rows of a table displayed in the user interface when scrolling the table.

16. The computer program product of claim 15 wherein the instructions and data configure the execution of the processor to:

provide a user option to freeze the display of selected columns including non-adjacent columns and/or selected rows including non-adjacent rows; and

receive first user input selecting at least one row or column for freezing.

17. The computer program product of claim 16 wherein the instructions and data configure the execution of the processor to:

receive second user input to scroll the display of the table; and

ensure the display of the selected at least one row or column when scrolling the display of the table.

18. The computer program product of claim 17 wherein the instructions and data configure the execution of the processor to:

determine additional columns and/or rows to paint with the columns and/or rows selected for freezing; and

display the additional columns and/or rows and the columns and/or rows selected for freezing.

19. The computer program product of claim 15 wherein the instructions and data configure the execution of the processor to freeze a border row and/or border column of the table when scrolling the display of the table.

20. The computer program product of claim 19 wherein the wherein the instructions and data define a UI control for displaying a table as a portion of a document being displayed on the display screen, which document is navigable by moving a focus to scroll the document and wherein the display of the table is invoked by scrolling to bring the UI control onto the display screen.

21. The computer program product of claim 20 wherein the instructions and data configure the execution of the processor to:

receive first user input scrolling the UI control on to the display at an edge of the display screen, aligning a respective edge portion of the table to be scrolled onto the display with the edge of the display screen; and

paint the border row and/or border column.
