    \section1 Supported Roles

    TableModelColumn supports all of \l {Qt::ItemDataRole}{Qt's roles},
    with the exception of \c Qt::InitialSortOrderRole.
    Roles can be accessed by as listed below, e.g.
    \code
    text: display

    required property string display
    \endcode

    \table
    \row \li Qt::DisplayRole \li display
    \row \li Qt::DecorationRole \li decoration
    \row \li Qt::EditRole \li edit
    \row \li Qt::ToolTipRole \li toolTip
    \row \li Qt::StatusTipRole \li statusTip
    \row \li Qt::WhatsThisRole \li whatsThis
    \row \li Qt::FontRole \li font
    \row \li Qt::TextAlignmentRole \li textAlignment
    \row \li Qt::BackgroundRole \li background
    \row \li Qt::ForegroundRole \li foreground
    \row \li Qt::CheckStateRole \li checkState
    \row \li Qt::AccessibleTextRole \li accessibleText
    \row \li Qt::AccessibleDescriptionRole \li accessibleDescription
    \row \li Qt::SizeHintRole \li sizeHintRoleNam
