Select multiple rows from table using Selenium in ruby

I'm writing script to automate test where I've to select multiple rows from table & apply some settings to those rows (by selecting them in a group). For that, I'll have to select multiple rows from table, but I'm not able to select those rows using Selenium.

I tried it using following code (CTRL+select the rows), but it's not working -

$driver.action.key_down(:control).perform
$driver.find_element(:xpath, ".//*[@id='1']/div/div/table/tbody/tr[1]").click
$driver.find_element(:xpath, ".//*[@id='2']/div/div/table/tbody/tr[2]").click
$driver.find_element(:xpath, ".//*[@id='3']/div/div/table/tbody/tr[3]").click

Following are web contents -

<div id="abc" class="unselectable dataTable" emptylineuptext="Lineup is Empty" ...>
  <div class="xyz">
    <div class="def" style="min-height: 3024px;">
      <table class="buffer" style="margin-top: 0px;">
       <tbody>
        <tr id="1" draggable="true">
        <td>
        <td>NA</td>
        </td>   
        </tr>

        <tr id="2" draggable="true">
        <td>
        <td>NA</td>
        </td>   
        </tr>

        <tr id="3" draggable="true">
        <td>
        <td>NA</td>
        </td>   
        </tr>

        <tr>
        .
        .
        .
        </tr>
    </tbody>
  </table>
</div>

Manually, I can select multiple rows from table. Could someone please tell me the solution?
