TMS中TColumnComboBox控件多列显示的用法(100分)

请教各位大虾，TMS中TColumnComboBox控件多列显示的用法，它的属性应该怎么设置

先要增加列，然后才能设置每项的值
TComboColumnItem *ColumnItem;
ColumnItem=CCBox1->Columns->Add();
ColumnItem->Width=75;
ColumnItem->Font->Style=TFontStyles()<<fsBold;

ColumnItem=CCBox1->Columns->Add();
ColumnItem->Width=75;

ColumnItem=CCBox1->Columns->Add();
ColumnItem->Width=50;
ColumnItem->Alignment=taRightJustify;
ColumnItem->Font->Color=clBlue;
ColumnItem->Font->Style=TFontStyles()<<fsBold;

TComboItem *ComboItem;
ComboItem=CCBox1->ComboItems->Add();
ComboItem->Strings->Add("BMW");
ComboItem->Strings->Add("CI323");
ComboItem->Strings->Add("1.200.000");

另外请问，您是否有此控件的源码，能不能给小弟一份
