QT QTableWidget導出爲Excel格式

本人親測有效，如果有問題希望大家能提出來。

Slot_ExportData()
{
	QString filepath = QFileDialog::getSaveFileName(this, tr("Save as..."),
		QString(), tr("EXCEL files (*.xls);;HTML-Files (*.txt);;"));

	if (filepath != "")
	{
		int row = m_pTable->rowCount();
		int col = m_pTable->columnCount();
		QList<QString> list;
		//添加列標題  
		QString HeaderRow;
		for (int i = 0; i < col; i++)
		{
			HeaderRow.append(m_pTable->horizontalHeaderItem(i)->text() + "\t");
		}
		list.push_back(HeaderRow);
		for (int i = 0; i < row; i++)
		{
			QString rowStr = "";
			for (int j = 0; j < col; j++){
				rowStr += m_pTable->item(i, j)->text() + "\t";
			}
			list.push_back(rowStr);
		}
		QTextEdit textEdit;
		for (int i = 0; i < list.size(); i++)
		{
			textEdit.append(list.at(i));
		}

		QFile file(filepath);
		if (file.open(QFile::WriteOnly | QIODevice::Text))
		{
			QTextStream ts(&file);
			ts.setCodec("GB2312");//這個地方大家自己判斷是否用“utf-8”
			ts << textEdit.document()->toPlainText();
			file.close();
		}
		//導出後將表格情況，這一步大家自己選擇要不要
		m_pTable->clearContents();
		m_pTable->setRowCount(0);
	}
