Google Apps Script :How to append a table in Document after a selection

Question

Is it possible to append a table after a selection in Google Document using Apps Script?

Only example I can find is this:

var body = DocumentApp.getActiveDocument().getBody();
var table = body.appendTable();

...which means to the end of document.

Thanks
EDIT:

How I make selection is:

var selection = doc.getSelection();

which is basicaly what is selected by mouse drag selection (blued out) on document editor.
From there I start to iterrate:

var elements = selection.getSelectedElements();  
var element = elements[0].getElement();
var startOffset = elements[0].getStartOffset();      // -1 if whole element  
var endOffset = elements[0].getEndOffsetInclusive(); // -1 if whole element 

This might be a part of PARAGRAPH.

Here is code that inserts a table at the current selection. It may need to be modified a little, but the point is; that it finds the child index of the body at the point of the selection.

function insertTableAtSelection() {
  // insert table as selection
  var theDoc = DocumentApp.getActiveDocument();
  var selection = theDoc.getSelection();
  Logger.log('selection: ' + selection);

  if (selection) {
    var elements = selection.getRangeElements();
    for (var i = 0; i < elements.length; i++) {
      var element = elements[i];
      Logger.log('element: ' + element.getElement());
    };

    var theElmt = element;
    var selectedElmt = theElmt.getElement();
    Logger.log('selectedElmt: ' + selectedElmt);

    var parent = selectedElmt.getParent();

    var insertPoint = parent.getChildIndex(selectedElmt);
    Logger.log('insertPoint: ' + insertPoint);    

    var body = theDoc.getBody();
    var table = body.insertTable(insertPoint + 1, [['one','two','three'],['yellow', 'green', 'red']]);
  };
};

The insertPoint is increased by one:

insertPoint + 1

That gets the table just beyond the selection.

For anyone reading this post who may want to adapt this code, keep in mind that this code only completes if there is a selection; the user needs to have highlighted some amount of content for there to be a selection.
