程序運行截圖如下：

原理，重寫QSortFilterProxyModel類中的filterAcceptsRow即可：

源碼如下：

mysortfilterproxymodel.h

#ifndef MYSORTFILTERPROXYMODEL_H #define MYSORTFILTERPROXYMODEL_H#include <QSortFilterProxyModel> #include <QRegExp>class MySortFilterProxyModel : public QSortFilterProxyModel {Q_OBJECT public:MySortFilterProxyModel(QObject *parent = 0);void setRxCol1(const QString rx);void setRxCol2(const QString rx);protected:bool filterAcceptsRow(int source_row, const QModelIndex &source_parent) const Q_DECL_OVERRIDE;private:QString m_rxCol1;QString m_rxCol2;};#endif // MYSORTFILTERPROXYMODEL_H
