In existing spreadsheet applications, a table reference requires an explicit cell range to be specified.
Various embodiments of the invention are disclosed in the following detailed description and the accompanying drawings.
The invention can be implemented in numerous ways, including as a process; an apparatus; a system; a composition of matter; a computer program product embodied on a computer readable storage medium; and/or a processor, such as a processor configured to execute instructions stored on and/or provided by a memory coupled to the processor. In this specification, these implementations, or any other form that the invention may take, may be referred to as techniques. In general, the order of the steps of disclosed processes may be altered within the scope of the invention. Unless stated otherwise, a component such as a processor or a memory described as being configured to perform a task may be implemented as a general component that is temporarily configured to perform the task at a given time or a specific component that is manufactured to perform the task. As used herein, the term ‘processor’ refers to one or more devices, circuits, and/or processing cores configured to process data, such as computer program instructions.
A detailed description of one or more embodiments of the invention is provided below along with accompanying figures that illustrate the principles of the invention. The invention is described in connection with such embodiments, but the invention is not limited to any embodiment. The scope of the invention is limited only by the claims and the invention encompasses numerous alternatives, modifications and equivalents. Numerous specific details are set forth in the following description in order to provide a thorough understanding of the invention. These details are provided for the purpose of example and the invention may be practiced according to the claims without some or all of these specific details. For the purpose of clarity, technical material that is known in the technical fields related to the invention has not been described in detail so that the invention is not unnecessarily obscured.
As used herein, the term “cell” refers to a cell associated with at least standard spreadsheet functionality. The term “at least standard spreadsheet functionality” in the context of a cell includes the ability to define the content of one cell in such a way that the content of the one cell is determined based at least in part on the content of one or more other cells, and the content of the one cell is updated automatically without further human action if the content of one or more of the one or more other cells is changed. As used herein, the term “host cell” refers to a cell in a formula editing mode, i.e., a cell into which a formula is being entered. In some embodiments, cells in a spreadsheet application are organized into one or more individual tables or table objects, each of which includes a desired number of rows and columns of cells. In such cases, a sheet or canvas of a spreadsheet document may include a desired number of table objects as well as any desired number of other objects such as charts, graphs, images, etc. Although in some of the examples described herein the cells of a spreadsheet application are organized into such table objects, the techniques described herein may be similarly employed with respect to other cell configurations or organizations, such as the (seemingly) infinite single grid or table of cells in each sheet of some typical spreadsheet applications that includes an unlimited (or very large) number of rows and columns of cells. Although many of the examples provided herein are with respect to a spreadsheet application, the techniques described herein may be similarly employed with respect to any application, spreadsheet or otherwise.
Whole table referencing without explicit cell ranges is disclosed. In some embodiments, the body cells of a table or all cells, including both body and header cells, of a table may be referred to by an identifier associated with the table and without use of any explicit cell ranges. Such a table reference remains valid and invariant even when the dimensions of an associated table are changed, e.g., as rows and/or columns of cells are deleted from and/or added to the table. In some embodiments, the context in which such a table reference is employed determines whether the table reference refers to just the body cells of the table or both the body and header cells of the table.
In various embodiments, a table reference that refers to a particular table may include a table identifier associated with the table, a sheet or canvas identifier associated with the sheet or canvas that includes the table, and/or a document identifier associated with the document that includes the table, for example, depending on whether the table reference is made within the same sheet or canvas that includes the table, in a different sheet or canvas in the same document, or in a different document. For example, a table reference to a table named “Grades” that is included in a sheet or canvas named “Fall 2008” and in a document named “Programming 101” may comprise any appropriate permutation, such as “Grades”, “Fall 2008::Grades”, “Programming 101::Grades”, and “Programming 101::Fall 2008::Grades”, that uniquely identifies the table in the context in which the reference is made.
A whole table reference without an explicit specification of a cell range is not only simpler to specify but is maintainable through table size variations. Such a whole table reference may be employed in any appropriate context, such as in a formula, as a function argument, in the source data definition of a chart or graph, etc. In some embodiments, a table reference may be represented in a formula (or other context) with a token, i.e., an atomic user interface object, rather than as plain text.
Like with cell or other references in spreadsheet applications, any context (e.g., a cell, formula, function, data source definition, graph, chart, etc.) that includes a table reference is dynamically updated (e.g., a formula is recalculated) in response to changes in the table such that current table values and/or properties are reflected in an associated calculation or computation. In some embodiments, for example, changes are pushed from a table object to all references of the table to facilitate the dynamic update.
Although the foregoing embodiments have been described in some detail for purposes of clarity of understanding, the invention is not limited to the details provided. There are many alternative ways of implementing the invention. The disclosed embodiments are illustrative and not restrictive.
