Meanwhile I have got an answer from Teacup Support Team.

CellStyles cannot be referred by index. They need to be referred to by name. Here is an example:

 
// removeTCStyles.jsx

if(app.documents.length > 0){ 
	var myDocument; 
	with (myDocument = app.activeDocument){ 
		cellStyles.everyItem().remove();  
		var styleNames = new Array(); 
		var count = 0; 
		var currentStyle = cellStyles.firstItem(); 
		while (currentStyle != null) { 
			styleNames[count] = currentStyle.name; 
			currentStyle = cellStyles.nextItem(currentStyle); 
			count++; 
		} 
		for (x in styleNames) { 
			myDocument.cellStyles.item(styleNames[x]).remove(); 
		} 
	} 
} 
else{ 
	alert("No documents are open. Please open a document and try again."); 
} 




To import Table- and CellStyles it is necessary to set the ReplaceOption to "ReplaceOption.overwrite" or "RaplaceOption.rename".

Here is an example for import of Styles:

 
// importTCStyles.jsx

var myDoc = app.documents[0]; 
var myFile = File.openDialog("Master of Table- and CellStyles");  
//myDoc.importTableStyles(myFile, ReplaceOption.overwrite); // imports TableStyles 
myDoc.importCellStyles(myFile, ReplaceOption.overwrite); // imports CellStyles 




But you have to take care that you don't import TableStyles and CellStyles at once: This will crash InDesign.
Importing only the TableStyles and importing CellStyles later works.

Nothing is perfect. ;-)
