QTableWidget的简单使用

QTableWidget是表格的一种表示，表格中的每一项都是用QTableWidgetItem来表示的。QTableWidget默认提供了水平表头和垂直表头，表头的索引从1开始。

我们先看看代码：

#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();}

运行如下图：

把注释去掉，运行如下图：

我们通过setHorizontalHeaderLabels来更改了表头。
