  • Patent number: 8887038
    Abstract: Various embodiments of systems and methods for extrapolating tabular structure to facilitate manipulation of elements in the freeform document are described herein. The freeform document includes an unstructured canvas providing users the ability to place one or more elements in the canvas. A primary column is determined by the selection of at least one element in the freeform document. Further, one or more secondary columns in the freeform document corresponding to the primary column are determined. A tabular structure in the freeform document is extrapolated based on the determined primary column and the one or more secondary columns to facilitate manipulation of elements in the freeform document, such as reordering, resizing and deleting the one or more elements, and inserting one or more new elements in the freeform document.
