Return promise inside the for loop

I have a logic like below,

getSpecificCell: function(tableObject, rowText, columnCss) {
    var ele = element.all(by.repeater(tableObject)).count().then(function(count) {
      for (var i = 0; i < count; i++) {
         return element(by.repeater(tableObject).row(i)).getText().then(function(txt) {
        if (txt.indexOf(rowText) !== -1) {
          return element(by.repeater(tableObject).row(i)).element(by.css('[' + columnCss + ']'));
        }
      });
    }
  });
  return ele;
}

But it is returning the value in first iteration itself. Is that possible to return the promise inside this kind of for loop or do we have any other solution for this?

First, you don't need to use for loops with an ElementArrayFinder. That's what the each() method is for.

Second, you shouldn't need to loop at all. It sounds like you should be using filter() to get the table cells that match your specification, though I'm not sure what exactly you're trying to accomplish.

var table = element.all(by.repeater(tableObject));
// list is an ElementArrayFinder of all elements that matched the filter
var list = table.filter(function (elem) {
    return elem.getText().then(function (text) {
        return txt.indexOf(rowText) !== -1
    })
});

// do something with list
list.count().then(function (count) {
    console.log(count);
});
