New row not coming with table properties with Apps script

Question

I tried to add a new row in an existing table inside Google doc file but the table property is not applied to the new row. I was able to save 2 cells with styling. Here's the Apps Script function

function addRow(fileId)
{
    var body = DocumentApp.openById(fileId).getBody(),
        searchElement = body.findElement(DocumentApp.ElementType.TABLE),
        element = searchElement.getElement(),
        table = element.asTable();

    var cell1Style = table.getRow(0).getCell(0).getAttributes();
    var cell2Style = table.getRow(0).getCell(1).getAttributes();

    cell1Style[DocumentApp.Attribute.BACKGROUND_COLOR] = '#ffffff';
    cell2Style[DocumentApp.Attribute.BACKGROUND_COLOR] = '#ffffff';

    var rowStyle = {};
    rowStyle[DocumentApp.Attribute.BORDER_COLOR] = '#000000';

    var tr = table.appendTableRow();
    tr.setAttributes(rowStyle);
    tr.appendTableCell('My Text:').setAttributes(cell1Style);
    tr.appendTableCell('My value').setAttributes(cell2Style);
}

Here's the document content after execution

As you can see the new row came outside the table even though i have set border color attribute. Please help

Here is how you do this:

function myFunction() {
  var body = DocumentApp.getActiveDocument().getBody();
  var table = body.findElement(DocumentApp.ElementType.TABLE).getElement().asTable();

  var newRow = table.appendTableRow();
  var lastRowAttributes = table.getRow(table.getNumRows()-1).getAttributes()

  newRow.appendTableCell("Text 1").setAttributes(lastRowAttributes);
  newRow.appendTableCell("Text 2").setAttributes(lastRowAttributes);
}

If that doesn't work for you, you can use:

function myFunction() {
  var body = DocumentApp.getActiveDocument().getBody();
  var table = body.findElement(DocumentApp.ElementType.TABLE).getElement().asTable();

  var lastRow = table.getRow(table.getNumRows()-1);

  var newRow = table.appendTableRow(lastRow.copy());

  newRow.getCell(0).setText("Text 1");
  newRow.getCell(1).setText("Text 2");
}

I decided to use the style of the last row (before appending) as the style for the following rows to save time.

Hope this helps!
