QTableWidget不能正常显示数据

Question

为什么我也设置了行数、行高，并且设置的信息也可以获取到，但窗口还是不显示设置的信息，请问这是为什么啊？

```c++
#include "bank_stuff.h"
#include "bankpushbutton.h"
#include "staff_function.h"

#include <QLabel>
#include <QMessageBox>
#include <QTableWidgetItem>
#include <QStringList>
#include <QPainter>
#include <QPropertyAnimation>
#include <QDebug>

bank_Stuff::bank_Stuff(QWidget *parent) : QTableWidget(parent)
{
    //设置窗口标题
    this->setWindowTitle("财大银行");
    //设置窗口图标
    this->setWindowIcon(QIcon(":/icon.jpg"));
    //设置窗口大小
    this->resize(400,600);

    //获取staffColumn
    creatStaffLink();

    //设置整体布局：行数，列数
    int column=2;
    this->setRowCount(staffColumn);
    this->setColumnCount(column);

    qDebug()<<"行 this->rowCount()="<<this->rowCount()<<endl;//行 this->rowCount()= 3 
    qDebug()<<"列 this->columnCount()="<<this->columnCount()<<endl;//列 this->columnCount()= 2 

    //设置每列的宽度都为该窗口二分之一
    this->setColumnWidth(0,this->width()/2);
    this->setColumnWidth(1,this->width()/2);

    //设置行高
    for(int i=0;i<staffColumn;i++)
        this->setRowHeight(i,this->height()/5);

    //设置列标签
    QStringList header;
    header<<"姓名"<<"电话";

    this->setHorizontalHeaderLabels(header);


    this->setItem(0,0,new QTableWidgetItem("张飞"));
    this->setItem(1,0,new QTableWidgetItem("关羽"));
    this->setItem(2,0,new QTableWidgetItem("吕布"));

    this->setItem(0,1,new QTableWidgetItem("35"));
    this->setItem(1,1,new QTableWidgetItem("36"));
    this->setItem(2,1,new QTableWidgetItem("32"));

    QString str = this->item(0,0)->text();
    qDebug()<<"str="<<str<<endl;//str= "张飞"

    //设置竖直滚动条
    this->setVerticalScrollBarPolicy(Qt::ScrollBarAlwaysOff);
}

void bank_Stuff::paintEvent(QPaintEvent *event)
{
    //绘制背景图片
    QPainter painter(this);
    QPixmap pix(":/background.jpg");

    painter.drawPixmap(0,0,this->width(),this->height(),pix);
}

```
