Description

CROSS-REFERENCE

This application is a continuation application of U.S. patent application Ser. No. 11/163,263, filed Oct. 12, 2005, the contents of which are incorporated by reference.

BACKGROUND OF THE INVENTION

The present invention relates to tables containing data and extracting specific data from the tables, and more particularly to a method and system for visually filtering a table using criteria from another table.
When working with tables, there is often a need to cross-filter columns of different tables containing the same type of data to extract certain desired information. One procedure is to simply apply a predetermined or form filter to a specific column in a table. However, this procedure may require access to a saved filter and manual alteration of the filter by the user. When the user is presented with multiple tables over which he desires to cross-reference data (for example, within a portal view), the need to efficiently extract data by applying filters based on a set of common data may be cumbersome and will typically require a series of steps to retrieve the desired information.

BRIEF SUMMARY OF THE INVENTION

In accordance with an embodiment of the present invention, a method for filtering a table may include creating a filter in response to a user selecting data in a first table. The method may also include applying the filter to at least one other table in response to a user selecting at least one column in the at least one other table.
In accordance with another embodiment of the present invention, a system for filtering a table may include a table filtering application operable on a processor for a user to visually filter a second table using criteria from a first table. The system may also include a data structure to create and apply a filter to the second table.
In accordance with another embodiment of the present invention, a computer program product for filtering a table may include a computer usable medium having computer usable program code embodied therein. The computer usable medium may include computer usable program code configured to create a filter in response to a user selecting data in a first table. The computer usable medium may also include computer usable program code configured to apply the filter to at least one other table in response to a user selecting at least one column in the at least one other table.

FIGS. 1A and 1B (collectively FIG. 1) are a flow chart of an example of a method 100 for filtering a table in accordance with an embodiment of the present invention. In block 102, any rows in a first table that contain data to be used to form a filter for filtering one or more other tables may be selected by a user. The data may be values, numbers, text or other information. In another embodiment of the present invention cells containing data to be used in forming a filter may be selected in a first table. The data selected in the cells or rows may also be contained in a selected column of interest. Referring also to FIG. 2, FIG. 2 illustrates a table 200 that will be used as an example to describe operation of the present invention to form a filter for filtering at least one other table in accordance with an embodiment of the present invention. In the exemplary table 200 assume information in at least one other table is of interest related to individuals whose last names are Andrews, Fraleigh and Robertson. Accordingly, rows 202 containing these last names in the column of interest, the column 204 labeled “Last Name,” may be selected. The rows 202 a, 202 b and 202 c containing these last names in the column 204 may be selected by clicking on a box 206 in a column 208 that may be labeled “Select” using a computer pointing device or mouse illustrated by the arrow 210 in FIG. 2. In another embodiment of the present invention, a cell 212 containing data to be used in the filter may be selected by a clicking operation using a computer pointing device or other means for selecting the specific cell 212 or cells of interest to be used in the filter. In other embodiments of the present invention, a row 202 or cell 212 containing data to be used in a filter may be selected by other means, such as those commonly used in association with computer systems or the like.
After selecting the cells or rows containing data of interest to be used in a filter for filtering one or more other tables, in block 104 (FIG. 1), the first table 200 may be reduced to include only the rows containing data to be used to form the filter. The reduced table may be presented to the user similar to that illustrated in FIG. 3A. FIG. 3A is an example of a reduced table 300 in response to selecting rows 202 or cells 212 in table 200 (FIG. 2) that contain data to form a filter for filtering another table in accordance with an embodiment of the present invention. The resulting rows 302 are illustrated in FIG. 3A.
Referring back to FIG. 1, in block 106, at least one column containing data to be used to filter one or more other tables may be selected. Referring also to FIG. 3B, FIG. 3B is an example of selecting a column 304 containing the data to form the filter in accordance with an embodiment of the present invention. In FIG. 3B, the column 304 containing the data of interest to be used in the filter may be labeled “Last Name” or other appropriate identification. The at least one selected column 304 may be highlighted or otherwise identified as illustrated by the dashed or broken line 306 in FIG. 3B around column 304. Highlighting or identifying the column 304 may serve to confirm the user's choice of the data to be used in the filter. The column 304 may be selected by a clicking operation or the like using a computer pointing device or the like as illustrated by the arrow 308 in FIG. 3B. For example, the computer pointing device 308 may be positioned over the column heading or anywhere on the column and then a right click operation may be performed by the user or a similar operation to select the column 304. The selected column 304 may then be highlighted or otherwise identified to confirm to the user's selection of the column 304.
While only a single column is illustrated as being selected to form the filter in FIG. 3B, under some circumstances data in more than one column may be of interest in forming a filter, in which case the present invention permits multiple columns to be selected.
Referring back to FIG. 1, in block 108, a filter or column filter containing the data of interest may be created in response to the user selecting one or more columns in the first table 200 or the reduced first table 300 (FIG. 3A). The filter may then contain data contained in intersections between any rows and the at least one column selected by the user in the first table 200. In another embodiment of the present invention, the filter may be created by populating the filter with data from cells at the intersections of selected rows and columns or data from just selected cells of the table.
In block 110, the resulting filter may be presented to the user in a predetermined format. FIG. 4 is an example of a filter 400 for filtering another table in accordance with an embodiment of the present invention. The filter 400 may be a result of selecting the rows and columns containing the data of interest as described above with reference to the examples shown in FIGS. 2-3A and 3B. In the block 110, means may be also provided for editing any data in the filter.
Referring back to FIG. 1, in block 112, at least one column in one or more other tables may be selected to which the filter may be applied. The filter generated by the method 100 may be applied to different types of tables. For example, even though the filter may be created from one type of table, the filter may be applied to other types of tables or spreadsheets, such as a Microsoft Excel table, a swing table or other types of spreadsheets.
Referring also to FIG. 5, FIG. 5 is an example of selecting a column 500 in another table 502 to which the filter may be applied in accordance with an embodiment of the present invention. The selected column 500 may be highlighted or otherwise identified as illustrated in FIG. 5 by the broken line 504. Highlighting or identifying the column 500 may confirm to the user the column 500 he has selected for applying the filter. The column 500 may be selected by positioning a computer pointing device or the like as represented by arrow 506 in FIG. 5 on the desired column 500 and performing a clicking operation, such as a right click or other function.
While only a single column 500 is illustrated as being selected to apply the filter in FIG. 5, under some circumstances data in more than one column may be of interest to apply the filter or the filter may be a multiple column filter, in such cases the present invention permits the selection of multiple columns in a table to which the filter may be applied.
Referring back to FIG. 1, in block 114, the filter may be applied to the at least one selected column. Any data in the filter may be matched to corresponding data in the at least one column. In block 116, the results of applying the filter may be presented. The results may be presented by presenting any rows in the table to which the filter was applied with data in the at least one selected column corresponding to data in the filter. FIG. 6 is an example of results 600 or a resulting table from applying the filter to the selected column 500 in the table 502 (FIG. 5) in accordance with an embodiment of the present invention. Only rows containing data matching data in the filter may be presented.
