Your buttons are submitting the form the are in, to not submit the form you'll have to use a type="button" button, also you've spelt getElementByID incorrectly its getElementById

<form>
    <table>
        <tr>
            <td><input id="input1" class="myText" type="text" placeholder="Row 1" /></td>
            <td><input id="input2" class="myText" type="text" placeholder="Row 1" /></td>
            <td><button type="button" onclick="toggleEnable('input1','input2')"> Enable/Disable </button></td>
        </tr>
        <tr>
            <td><input id="input3" class="myText" type="text" placeholder="Row 3" /></td>
            <td><input id="input4" class="myText" type="text" placeholder="Row 4" /></td>
            <td><button type="button" onclick="toggleEnable('input3','input4')"> Enable/Disable </button></td>
        </tr>
    </table>
</form>

    function toggleEnable(el1, el2) {
        document.getElementById(el1).disabled = true;
        document.getElementById(el2).disabled = true;
    }

function toggleEnable(id) {
   var textbox = document.getElementById(id);
   
   if (textbox.disabled) {
      // If disabled, do this 
       document.getElementById(id).disabled = false;
    } else {
       // Enter code here
        document.getElementById(id).disabled = true;
     }
}

<form>
    <table>
        <tr>
            <td><input id="input1" class="myText" type="text" placeholder="Row 1" /></td>
            <td><button type="button" onclick="toggleEnable('input1')"> Enable/Disable </button></td>
        </tr>
        <tr>
            <td><input id="input2" class="myText" type="text" placeholder="Row 2" /></td>
            <td><button type="button" onclick="toggleEnable('input2')"> Enable/Disable </button></td>
        </tr>
    </table>
</form>
