           {Spreadsheet application with table view showing cells and headers}

    The example demonstrates how to combine TableView and HeaderView to
    create a spreadsheet application.

    \section1 Overview
    The spreadsheets example demonstrates how to combine TableView and
    HeaderView to create a spreadsheet application. It serves as an
    excellent starting point for developers looking to understand the
    implementation of spreadsheet-like functionality in their
    applications, highlighting the versatility of TableView and
    HeaderView while providing practical insights into handling user
    interactions and data operations in a grid-based interface.

    This example implements a comprehensive set of functionalities,
    providing users with a robust set of tools for data manipulation
    and structural organization. These functionalities include:
    \list
        \li Cell Manipulation
        \li Data Management
        \li Formula Support
    \endlist

    \section1 Cell Manipulation
    This feature set focuses on how users can interact with and modify
    the structure of the spreadsheet. Key capabilities in this area
    include:
    \list
        \li Select individual cells, entire rows, or columns
        \li Insert and remove rows and columns
        \li Show or hide specific rows and columns
    \endlist

    \section1 Data Management
    These features demonstrate advanced data handling capabilities,
    allowing users to efficiently manipulate cell contents. The
    following operations are supported:
    \list
        \li Copy, cut, and paste groups of cells
        \li Drag and drop cell contents
        \li Reorder rows and columns
    \endlist

    \section1 Formula Support
    This section highlights the spreadsheet's ability to perform
    calculations, enabling users to create dynamic, interconnected
    data. The supported operations include:
    \list
        \li Perform basic arithmetic operations
        \li Calculate sum of a range of cells
    \endlist

    \section2 Perform basic arithmetic operations
    This subsection covers the fundamental mathematical operations that
    can be performed within cells. Users can leverage the following
    capabilities:
    \list
        \li Single cell assignment
        \li Addition and subtraction
        \li Multiplication and division
    \endlist

    \section2 Calculate sum of a range of cells
    The summation feature allows users to quickly total a series of
    values. Users can employ a formula syntax similar to common
    spreadsheet applications. For example, to sum the values in cells
    A1 through B4, one might use a formula like "=SUM A1:B4"
