hiding crosstab columns in BIRT when format is excel

问题

I want to hide two of the crosstab columns based on some condition. I have been able to achieve it by using

 function onPrepareCell( cell, reportContext )
 if(some condition){
    if( cell.getCellID() == cell#){
    cell.getStyle().setDisplay("none");
    }
  }

in the onPrepare event of cross tab. It works fine in PDF,HTML format but the columns are not getting hidden when the format is Excel. I need to get this done soon please help

I got the answer from BIRT exchange i am posting the answer here so that it may be helpful to others

In the onPrepare() event of crosstab you can write the code as given below

function onPrepareCrosstab( crosstab, reportContext ) {
if(some condition ){ reportContext.getDesignHandle().getElementByID(ElementId#).setStringProperty("width","0px"); }

}

here ElementId# is the Id# of the cell you want to hide. As you can see we can also use this to change the width of the cell dymanically.

Try your code in an OnCreateCell event.
