How do I clear cell attributes not defined by a cell style in InDesign CS5?

I should add that I am working with Visual Basic, so find the discussion in javascript a bit difficult.

Hi Uwe,

[JS] to make Tables really "pure"!

Thanks for your comments! 

At the beginning: All kind of situations

First approach: the op keeps the cell styles manually applied but, now, really pure!

(the "yellow" cell in the first table was a "red" cell!)

app.doScript("main()", ScriptLanguage.javascript, undefined, UndoModes.FAST_ENTIRE_SCRIPT, "Pure Tables! …");  
  
function main()  
{ 
    
   var  myDoc = app.activeDocument,  
        myCells = myDoc.textFrames.everyItem().tables.everyItem().cells.everyItem().getElements(),  
        C = myCells.length;  
        while( C-- ) 
            {
                myCells.clearCellStyleOverrides(); 
                myCells.texts[0].clearOverrides(); 
            }   
}

Second approach: Totally "pure" tables!

app.doScript("main()", ScriptLanguage.javascript, undefined, UndoModes.FAST_ENTIRE_SCRIPT, "Pure Tables! …");  
  
function main()  
{ 
    
var  myDoc = app.activeDocument,  
     myCells = myDoc.textFrames.everyItem().tables.everyItem().cells.everyItem().getElements(),  
     C = myCells.length;  
        while( C-- ) 
            {
                myCells.clearCellStyleOverrides(); 
                myCells.appliedCellStyle = "[None]"; 
                myCells.texts[0].clearOverrides(); 
            }   
}
