How to Add RTL Tables to a Google Document

As I’m trying to format google doc tables and in reference to this thread I was able to add some formatting to the header row, to the table data and was able to create a doc in a landscape layout.

However, I still didn’t find a solution to:

Making all the table cells to be RTL (it seems like I can only RTL paragraphs)

Here is the code I have so far

function createDoc() {
  var ssUrl = 'https://docs.google.com/spreadsheets/d/1ZWbAOdOfRSJtrfmLWjX6Q6cPT-YztII_uVdsBzWcQ_I/edit#gid=1116846206';
  var sheetName = 'paycall';   // name of sheet to use

   var values = SpreadsheetApp.openByUrl(ssUrl)
                             .getSheetByName(sheetName)
                             .getDataRange()
                             .getDisplayValues();


  var doc = DocumentApp.create('Sample Document 1');
  var body = doc.getBody();
  body.setPageHeight(595).setPageWidth(842);

  var tableStyle = {}; 
   tableStyle[DocumentApp.Attribute.FONT_SIZE] = 10; 

  var rowsData = values;
  body.insertParagraph(0, doc.getName())
      .setHeading(DocumentApp.ParagraphHeading.HEADING1).setLeftToRight(false);
  table = body.appendTable(rowsData).setAttributes(tableStyle);
  table.getRow(0).editAsText().setFontSize(12).setBold(true).a;


}

function table(){
  Code: var cells = [ ["EnglishTitle", "HebrewTitle"], ["Text", ""] ]; 
  var tableStyle = {}; 
  tableStyle[DocumentApp.Attribute.FONT_FAMILY] = DocumentApp.FontFamily.TIMES_NEW_ROMAN;
  tableStyle[DocumentApp.Attribute.FONT_SIZE] = 12; 
  var doc = DocumentApp.getActiveDocument().getBody();
  doc.appendTable(cells).setAttributes(tableStyle).getCell(1,1).insertParagraph(0, "Top line not moved. nText Should Be Right to left, but it's not, nThis text is correctly on the right.").setLeftToRight(false).appendText('nThis is the appended text,ncorrectly set right to left.');
}
