     columns.get(i).sendKeys(protractor.Key.ENTER);

 browser.sleep(3000);

All lines of code you placed are promises, so you first need to resolve each of them before you can use the result. For example, columns.get(i).getText() is a Promise, you first need to do the following before you can use the value

columns.get(i).getText()
    .then(function(tdText){
        console.log('tdText = ',tdText);
    });

You can also use a filter method on all the td 's like this, see the Protractor documentation :

// Get all the columns in a table, this will resolve in a ElementArrayFinder
// The filter will loop over each element in the ElementArrayFinder
$$('table td').filter(function(elem, index) {
  // For each found td, get the text
  return elem.getText().then(function(text) {
    // when a match is found, return it, else go to the next element
    return text === '13';
  });
// If an element is found based on the text it will return an ElementArrayFinder
// with 1 result, get the first element and for example click on it
}).first().click();

Hope this helps
