问题：在CListCtrl中第一列元素只能左对齐，下面是msdn中的说明!

CListCtrl::InsertColumn

Inserts a new column in a list view control.

int InsertColumn(
int nCol,
const LVCOLUMN* pColumn
);
int InsertColumn(
int nCol,
LPCTSTR lpszColumnHeading,
int nFormat = LVCFMT_LEFT,
int nWidth = -1,
int nSubItem = -1
);
Parameters
nCol
The index of the new column.
pColumn
Address of an LVCOLUMN structure that contains the attributes of the new column.
lpszColumnHeading
Address of a string containing the column's heading.
nFormat
Integer specifying the alignment of the column. It can be one of these values: LVCFMT_LEFT, LVCFMT_RIGHT, or LVCFMT_CENTER.
nWidth
Width of the column, in pixels. If this parameter is -1, the column width is not set.
nSubItem
Index of the subitem associated with the column. If this parameter is -1, no subitem is associated with the column.
Return Value
The index of the new column if successful or -1 otherwise.

Remarks
The leftmost column in a list view control must be left-aligned.

The LVCOLUMN structure contains the attributes of a column in report view. It is also used to receive information about a column. This structure is described in the Platform SDK.

解决方法：
方法1:
1、在第一列插入一个空列
2、设置第一列的宽度为0
3、然后插入位置从1开始

例子代码：
m_pListCtrl.InsertColumn (0, "",LVCFMT_CENTER);
m_pListCtrl.InsertColumn (1, "Element",LVCFMT_LEFT);
m_pListCtrl.InsertColumn (2, "Note",LVCFMT_LEFT);

m_pListCtrl.SetColumnWidth (0, 0);
m_pListCtrl.SetColumnWidth (1, ClientRect.Width() / 5);
m_pListCtrl.SetColumnWidth (2, LVSCW_AUTOSIZE_USEHEADER);

方法2：
1、首先多添加一列
2、当所有列添加完成以后，删除第一列即可
例子代码：
m_List.InsertColumn (0, "dummy", LVCFMT_CENTER);//多添加一列
m_List.InsertColumn (1, "Element", LVCFMT_CENTER);
m_List.InsertColumn (2, "Note", LVCFMT_LEFT);

m_List.DeleteColumn(0);

m_List.SetColumnWidth (0, ClientRect.Width() / 5);
m_List.SetColumnWidth (1, LVSCW_AUTOSIZE_USEHEADER);
