　　今天写了一个CellRenderer，实现自定义Flash的DataGrid组件中字体的外观，使其支持hmtl格式。文件如下：

文件名：HtmlCellRenderer.as

/****************************************************************************

class HtmlCellRenderer extends mx.core.UIComponent
{
private var HtmlLabel;
private var owner;
private var listOwner;
private static var PREFERRED_HEIGHT_OFFSET = 4;
private static var PREFERRED_WIDTH = 100;
private var startDepth:Number = 1;

public function HtmlCellRenderer()
{
}

  var c = HtmlLabel = this.createLabel("HtmlLabel", startDepth);
  c.styleName = listOwner;
  c.selectable = false;
  c.tabEnabled = false;
  c.background = false;
  c.border = false;
  c.html=true;
  size();
}

public function size():Void
{
var c = HtmlLabel;
c.setSize(__width, __height);
}

public function getPreferredHeight():Number
{
return owner.__height + PREFERRED_HEIGHT_OFFSET;
}

public function setValue(suggestedValue:String, item:Object, selected:Boolean):Void
{
  if (item==undefined){
   HtmlLabel._visible = false;
  }
  HtmlLabel.htmlText = suggestedValue;
}
}

用法：myDataGrid.getColumnAt(i).cellRenderer = "HtmlCellRenderer";

效果如图所示：
