qt把map中的值插入到tableView

要将`map`中的值插入到`QTableView`中，你需要创建一个自定义的`QAbstractTableModel`子类，并将其作为数据模型。以下是一个示例代码，演示了如何将`map`中的值插入到`QTableView`中：

#include <QApplication>
#include <QTableView>
#include <QAbstractTableModel>
#include <QMap>

class MapTableModel : public QAbstractTableModel
{
public:
    explicit MapTableModel(const QMap<QString, QVariant>& map, QObject* parent = nullptr)
        : QAbstractTableModel(parent), m_map(map)
    {
    }

    int rowCount(const QModelIndex& parent = QModelIndex()) const override
    {
        Q_UNUSED(parent)
        return m_map.size();
    }

    int columnCount(const QModelIndex& parent = QModelIndex()) const override
    {
        Q_UNUSED(parent)
        return 2;  // Assuming two columns: key value
    }

    QVariant data(const QModelIndex& index, int role = Qt::DisplayRole) const override
    {
        if (!index.isValid())
            return QVariant();

        if (role == Qt::DisplayRole)
        {
            if (index.column() == 0)  // Key column
                return m_map.keys().at(index.row());
            else if (index.column() == 1)  // Value column
                return m_map.values().at(index.row());
        }

        return QVariant();
    }

    QVariant headerData(int section, Qt::Orientation orientation, int role = Qt::DisplayRole) const override
    {
        if (role == Qt::DisplayRole && orientation == Qt::Horizontal)
        {
            if (section == 0)
                return QStringLiteral("Key");
            else if (section == 1)
                return QStringLiteral("Value");
        }

        return
