【场景】套打时，内容为空时不打印边线
【案例】通过套打脚本配置实现
```python
import clr
clr.AddReference("System.Drawing")
clr.AddReference("Kingdee.BOS.Core")
clr.AddReference("DevExpress.Data.v13.1")
from System.Drawing import *
from Kingdee.BOS.Core import *
from DevExpress.XtraPrinting import BorderSide
def OutputElement(e):
if(len(e.ControlInfo.Text.strip()) >0):
return;
e.ControlInfo.DevBrick.Style.Sides = BorderSide.None;
```
【效果】内容为空时，边线不会出来
