QTableWidget的水平表头和垂直表头的设定

QTableWidget默认提供了水平表头和垂直表头，表头的索引从1开始。

#include <QApplication>
#include <QTableWidget>
#include <QHBoxLayout>
int main(int argc, char** argv)
{
	QApplication app(argc, argv);
	QTableWidget* tableWidget = new QTableWidget;
	tableWidget->setWindowTitle("QTableWidget");
	tableWidget->resize(350, 250);
	tableWidget->setRowCount(6);
	tableWidget->setColumnCount(3);
/*
	QStringList header;
	header.append("One");
	header.append("Two");
	tableWidget->setHorizontalHeaderLabels(header);
*/
	tableWidget->setItem(0,0, new QTableWidgetItem("A"));
	tableWidget->setItem(1,0, new QTableWidgetItem("B"));
	tableWidget->setItem(2,0, new QTableWidgetItem("C"));
	tableWidget->setItem(3,0, new QTableWidgetItem("D"));
	tableWidget->setItem(4,0, new QTableWidgetItem("E"));
	tableWidget->setItem(0,1, new QTableWidgetItem(QIcon("images/data.png"), "data"));
	tableWidget->setItem(1,1, new QTableWidgetItem(QIcon("images/decision.png"), "decision"));
	tableWidget->setItem(2,1, new QTableWidgetItem(QIcon("images/document.png"), "document"));
	tableWidget->setItem(3,1, new QTableWidgetItem(QIcon("images/printer.png"), "printer"));
	tableWidget->setItem(4,1, new QTableWidgetItem(QIcon("images/process.png"), "process"));
	tableWidget->show();
	return app.exec();
}

把注释去掉，运行如下图：

 

 

我们通过setHorizontalHeaderLabels来更改了水平表头。
