设置CListCtrl表头图像~

	m_List.SetExtendedStyle(LVS_EX_FULLROWSELECT );
	m_List.InsertColumn(0, _T("网址"), LVCFMT_LEFT, 100 );
	m_List.InsertColumn(1, _T("说明"), LVCFMT_LEFT, 100 );
	m_List.InsertColumn(3, _T("耗时"), LVCFMT_LEFT, 100 );

	LVCOLUMN lvColumn;
    CImageList *ImgHeaders = new CImageList;
    ImgHeaders->Create(16,16,ILC_MASK,1,1);
    ImgHeaders->Add(AfxGetApp()->LoadIcon(IDI_UP));
    ImgHeaders->Add(AfxGetApp()->LoadIcon(IDI_DOWN));
	
    m_List.SetImageList(ImgHeaders, LVSIL_SMALL);
	
    lvColumn.mask = LVCF_FMT | LVCF_IMAGE;  //mask说明此结构中哪些成员是有效的
    lvColumn.fmt = LVCFMT_LEFT | LVCFMT_IMAGE;  //列的对齐方式
    lvColumn.iImage = 0;
	m_List.SetColumn(0,&lvColumn);
	lvColumn.iImage = 1;
    m_List.SetColumn(1,&lvColumn);

上面的显示不正常

补上正确的
