Detailed Description

Model for the access to a Table.

This is a model in the sense of Qt4 model/view framework which is used to access a Table object from any of Qt4s view classes, typically a QTableView. Its main purposes are translating Table signals into QAbstractItemModel signals and translating calls to the QAbstractItemModel read/write API into calls in the public API of Table. In many cases a pointer to the addressed column is obtained by calling Table::column() and the manipulation is done using the public API of column.

enum TableModel::CustomDataRole

Enumerator:

MaskingRole	bool determining whether the cell is masked
FormulaRole	the cells formula
CommentRole	the column comment (for headerData())
