executing a formula engine to determine a calculation definition in response to the user formula value and the document object model, wherein the calculation definition comprises requirements for operations of an executable model to implement the user formula value; and

further comprising generating an executable object in response to the calculation definition, wherein the executable object comprises instructions which, upon execution, cause at least one of a document server and a first client computing device to perform operations in response to the calculation definition, and wherein the instructions comprise a column-wise operation in response to the user formula value comprising a table column reference.

10. The method of claim 9 , wherein the column-wise operation comprises applying the user formula value to an entire column of a table.

11. The method of claim 10 , wherein a column-wise operation is applied to a column with a drag-and-drop operation of the user formula value to the column.

12. The method of claim 9 , further comprising:

interpreting a first user input comprising a text flow entry;

interpreting a second user input comprising a table-based calculation entry;

positioning a text entry value on a unified document surface in response to the first user input;

creating at least one data structure in response to the table-based calculation entry; and

positioning the at least one data structure on the unified document surface.

13. The method of claim 9 , wherein the column-wise operation comprises applying the user formula value to an entire data column of a table with a single entry of a formula.

14. The method of claim 9 , further comprising selecting an entire column of a table in response to the user formula value referencing a column.

15. The method of claim 9 , further comprising generating an executable object in response to the calculation definition, and wherein the executable object comprises instructions which, upon execution, cause at least one of the document server and the first client computing device to perform operations in response to the calculation definition.

16. A non-transient computer readable medium containing program instructions for causing a computer to perform the method of:

executing a document object model, wherein the document object model comprises an object definition corresponding to each of a plurality of objects in a document;
