Protractor: Unable to access a row and its column from a table

<div class="k-grid-content">
    <table>
        <tbody>
            <tr>
                <td>row1Col1</td>
                <td>row1Col2</td>
                <td>row1Col3</td>
            </tr>

            <tr>
                <td>row2Col1</td>
                <td>row3Col2</td>
                <td>row4Col3</td>
            </tr>

            <tr>
                <td>row3Col1</td>
                <td>row3Col2</td>
                <td>row3Col3</td>
            </tr>

        </tbody>
    </table>
 </div>

var grid = element.all(by.css('.k-grid-content tr')); //this will return row1,row2,row3

but I am unable to use code below to get each row and its column.

grid.each.each(function(row){
    var rowElems = row.findElements(by.tagName('td'));
    expect(rowElems.get(0).getText()).toMatch('/Col1/');
});

the following error message is displaying. Message: TypeError: Object [object Object] has no method 'findElements'
