// <synopsis>
// TableRowProxy gives access to row-based table accessor functions.
// It is primarily meant to be used in classes that wrap access to it
// from scripting languages (like Glish and Python).
// However, it can also be used directly from other C++ code.
//
// A TableRowProxy object is usually created by class
// <linkto class=TableProxy>TableProxy</linkto>.
// </synopsis>

// Construct for the given columns in the table.
