Left and right border for empty cell in pdf table

[AlGraf]

I try to make pdf table like this:
[PdfTableExample][1]

[1]: https://i.stack.imgur.com/in0Yr.png

I need if header1 and header2 in line is null - make only left border(or right for htader2)
else make all border except bottom.
My code is:
For header1:

    data.#subform[0].Table1.Row1.MANDT::ready:layout - (JavaScript, client)
//"0" is the top border, 
//"1" is the right border, 
//"2" = bottom and 
//"3" is the left border
if ( this.rawValue == null )
{
//TextField.Border
//  this.ui.oneOfChild.border.getElement("edge",0).presence = "invisible";
//  this.ui.oneOfChild.border.getElement("edge",1).presence = "invisible";
//  this.ui.oneOfChild.border.getElement("edge",2).presence = "invisible";
//  this.ui.oneOfChild.border.getElement("edge",3).presence = "invisible";
//////////////////////////////////////////////////////////////////////////

    this.border.getElement("edge",0).presence = "invisible";
//  this.ui.oneOfChild.border.getElement("edge",1).presence = "invisible";
    this.border.getElement("edge",2).presence = "invisible";
//  this.ui.oneOfChild.border.getElement("edge",3).presence = "invisible";



}
else 
{
////TextField.Border
//  this.ui.oneOfChild.border.getElement("edge",0).presence = "invisible";
//  this.ui.oneOfChild.border.getElement("edge",1).presence = "invisible";
//  this.ui.oneOfChild.border.getElement("edge",2).presence = "invisible";
//  this.ui.oneOfChild.border.getElement("edge",3).presence = "invisible";
//////////////////////////////////////////////////////////////////////////

//  this.border.getElement("edge",0).presence = "invisible";
//  this.ui.oneOfChild.border.getElement("edge",1).presence = "invisible";
    this.border.getElement("edge",2).presence = "invisible";
//  this.ui.oneOfChild.border.getElement("edge",3).presence = "invisible";
}

For header2:

 data.#subform[0].Table1.Row1.MATNR::ready:layout - (JavaScript, client)
//"0" is the top border, 
//"1" is the right border, 
//"2" = bottom and 
//"3" is the left border
if ( this.rawValue == null )
{
//TextField.Border
//  this.ui.oneOfChild.border.getElement("edge",0).presence = "invisible";
//  this.ui.oneOfChild.border.getElement("edge",1).presence = "invisible";
//  this.ui.oneOfChild.border.getElement("edge",2).presence = "invisible";
//  this.ui.oneOfChild.border.getElement("edge",3).presence = "invisible";
//////////////////////////////////////////////////////////////////////////

    this.border.getElement("edge",0).presence = "invisible";
//  this.ui.oneOfChild.border.getElement("edge",1).presence = "invisible";
    this.border.getElement("edge",2).presence = "invisible";
//  this.ui.oneOfChild.border.getElement("edge",3).presence = "invisible";



}
else 
{
////TextField.Border
//  this.ui.oneOfChild.border.getElement("edge",0).presence = "invisible";
//  this.ui.oneOfChild.border.getElement("edge",1).presence = "invisible";
//  this.ui.oneOfChild.border.getElement("edge",2).presence = "invisible";
//  this.ui.oneOfChild.border.getElement("edge",3).presence = "invisible";
//////////////////////////////////////////////////////////////////////////

//  this.border.getElement("edge",0).presence = "invisible";
//  this.ui.oneOfChild.border.getElement("edge",1).presence = "invisible";
    this.border.getElement("edge",2).presence = "invisible";
//  this.ui.oneOfChild.border.getElement("edge",3).presence = "invisible";
}

Why when header1 and header2 is null i cannot see left/right border?
