I found a previous post that is helping me with this.



// Paragraph inside of table. 
var oPgf = app.selection[0].paragraphs[0]; 
// Make sure the paragraph is inside a table 
if (oPgf.parent.constructor.name === "Cell") { 
  var oCell = oPgf.parent; 
  var oTbl = oCell.parent; 
  // Get the paragraph containing the table anchor. 
  var oPgf2 = oTbl.storyOffset.paragraphs[0]; 
  // Loop from the table anchor to the top of the story. 
  while (oPgf2) { 
    $.writeln(oPgf2.constructor.name); 
    oPgf2 = oPgf2.parentStory.paragraphs.previousItem(oPgf2); 
  } 
}



This basically works, except this line gives an "Object is invalid" error when it gets to the beginning of the story:



oPgf2 = oPgf2.parentStory.paragraphs.previousItem(oPgf2);



I can use a try statement, but I am wondering why the loop doesn't exit gracefully without an error. Thanks.
