qt做的表格，怎么让一列变颜色！并且列有拖曳的功能，即可以把第一列拖到第三列。



哪位哥哥说说呀？多多谢谢了

我会了。class SpreadSheetItem : public QTableWidgetItem；
SpreadSheetItem  是QTableWidgetItem 子类


void SpreadSheet::setupContents()
{
    QColor titleBackground(Qt::lightGray);//green
    QFont titleFont = table->font();
    titleFont.setBold(true);

    // column 0
    table->setItem(0, 0, new SpreadSheetItem("Item"));
    table->item(0, 0)->setBackgroundColor(titleBackground);
    table->item(0, 0)->setToolTip("This column shows the purchased item/service");
    table->item(0, 0)->setFont(titleFont);
    table->setItem(1, 0, new SpreadSheetItem("AirportBus"));
    table->setItem(2, 0, new SpreadSheetItem("Flight (Munich)"));
    table->setItem(3, 0, new SpreadSheetItem("Lunch"));
                                                   table->setItem(4, 0, new SpreadSheetItem("Flight (LA)"));
    table->setItem(5, 0, new SpreadSheetItem("Taxi"));
    table->setItem(6, 0, new SpreadSheetItem("Dinner"));
    table->setItem(7, 0, new SpreadSheetItem("Hotel"));
    table->setItem(8, 0, new SpreadSheetItem("Flight (Oslo)"));
    table->setItem(9, 0, new SpreadSheetItem("Total:"));
    table->item(9, 0)->setFont(titleFont);
    table->item(9,0)->setBackgroundColor(Qt::lightGray);
    //===================================
    //column color
    for (int i = 1;i < 9; i++)
    {
        table->item(i,0)->setBackgroundColor(Qt::yellow);
    }
    //=========================================================
    // column 1
    table->setItem(0, 1, new SpreadSheetItem("Date"));
    table->item(0, 1)->setBackgroundColor(titleBackground);
    table->item(0, 1)->setToolTip("This column shows the purchase date, double click to change");
    table->item(0, 1)->setFont(titleFont);
    table->setItem(1, 1, new SpreadSheetItem("15/6/2006"));
    table->setItem(2, 1, new SpreadSheetItem("15/6/2006"));
    table->setItem(3, 1, new SpreadSheetItem("15/6/2006"));
    table->setItem(4, 1, new SpreadSheetItem("21/5/2006"));
    table->setItem(5, 1, new SpreadSheetItem("16/6/2006"));
    table->setItem(6, 1, new SpreadSheetItem("16/6/2006"));
    table->setItem(7, 1, new SpreadSheetItem("16/6/2006"));
    table->setItem(8, 1, new SpreadSheetItem("18/6/2006"));
    table->setItem(9, 1, new SpreadSheetItem());
    table->item(9,1)->setBackgroundColor(Qt::lightGray);
