Get Max. Panel based on Table Height

Hi,

I wanted to create a panel with 'n' number of columns based on the table columns. But as of now I have get only 13 columns. Please guide me to add columns as many as based on the table column length.

		var sCancel = { en: "Cancel"};
    if ( app.activeDocument ) {
	//app.doScript( autoSpalte, undefined, undefined, UndoModes.ENTIRE_SCRIPT, localize(sAutoColumn) );
var tables = app.activeDocument.stories.everyItem().tables.everyItem();
	for(myCounter = 0; myCounter < app.activeDocument.activeLayer.textFrames.length; myCounter++)
	{
        // alert("TextFrame : " + app.activeDocument.activeLayer.textFrames.item(myCounter).contents);
         myStory = app.activeDocument.activeLayer.textFrames.item(myCounter);
      myStory.fit(FitOptions.frameToContent); 
      //  alert(myStory.fit(FitOptions.frameToContent))
		if (myStory.constructor.name == "TextFrame")
		{  
		for( var j = 0; j< myStory.tables.length ; j++ ) 
		{
      myStory.fit(FitOptions.frameToContent); 
      
            var myColumnCount = myStory.tables[j].columns.length
					for( var i = 0; i< myStory.tables[j].columns.length ;i++ ) 
			{
           //     alert(myStory.tables[j].columns.length)
          // alert("Width" + myStory.textFramePreferences.textColumnFixedWidth)
          // alert("Left"+ myStory.tables[j].cells[i].leftInset)
           //alert("Right" + myStory.tables[j].cells[i].rightInset)
           if (myStory.constructor.name == "TextFrame")
		{  
		myFrameWidth = myStory.textFramePreferences.textColumnFixedWidth-myStory.tables[j].cells[i].leftInset-myStory.tables[j].cells[i].rightInset;
       }
	 else {
		// 210208 Edit: try to get column width instead of simply textframe width
		try {
         //   alert(myStory)
			myFrameWidth = myFrame.textFramePreferences.textColumnFixedWidth;
            
		} catch(e) {
			myFrameWidth = myStory.geometricBounds[3] - myStory.geometricBounds[1];
