QT TableWidget的使用1：簡單使用
阿新 • • 發佈：2019-02-14
其實就是幾行.
建立行，從第一行開始建立
ui->tableWidget->insertRow(i); //i代表行數，從0開始
ui->tableWidget->setItem(i,j,newQTableWidgetItem(QString::number(D[i].x))); 第I行第J列，最後傳的數值只能為QString
一個例項，從excel中讀取資料並放進QTableWidget顯示
structdata{
intx;
inty;
QStringmonth;
QStringday;
floatFFMC;
floatDMC;
floatDC;
floatISI;
floattemp;
intRH;
floatwind;
floatrain;
floatarea;

QAxObject*workbooks=excel.querySubObject("WorkBooks");
workbooks->dynamicCall("Open(constQString&)",QString("c:/dd.xls"));
QAxObject*workbook=excel.querySubObject("ActiveWorkBook");//獲取活動工作簿
QAxObject*worksheets=workbook->querySubObject("WorkSheets");//獲取所有的工作表,如圖
intintCount=worksheets->property("Count").toInt();//獲取了表的個數
//qDebug()<<intCount;//輸出工作表的個數
QAxObject*worksheet=workbook->querySubObject("WorkSheets(int)",1);//獲取第一個工作表
//QAxObject*range=worksheet->querySubObject("Cells(int,int)",1,1);//獲取cell的值
