Hubspot Email templating not responsive in Gmail app

Question

Currently, I'm working on an e-mail template in HubSpot but I came across a problem that I can't seem to find a fix for.

<table class="two-col-centered" style="line-height: 1.5em; max-height: 309px;">
<tr>
    <td style="width: 40%; font-size: 12px; padding: 0px 0px 0px 0px;" valign=top class="k-700-col mk-padding">
        <table style="width: 100%;"><tr>
            <td style="padding: 0px 0px 0px 00px;">
                {% if widget.Image.src %}
                    <img src="{{ widget.Image.src }}" width="309px;" height="269px" alt="{{ widget.Image.alt }}">
                {% endif %}
            </td>
        </tr></table>
    </td>

    <td style="width: 60%; font-size: 12px; padding: 0; background-color: #ED4A2F;" valign=top class="k-700-col mk-padding;">
        <table style="width: 100%;"><tr>
            <td style="padding: 25px 30px;">
                <h2 style="font-size: 20px; margin: 0; margin-bottom: 10px; color: #fff;">{{ widget.heading_right }}</h2>
                <span style="display: block; background-color: #fff; width: 5em; height: 5px;  border: none;"></span>
                {{ widget.content_right }}
                {{ widget.CTA }}
            </td>
        </tr>
        </table>
    </td>

</tr>

This is the code currently in HubSpot for the particular part that isn't responsive in the Gmail app.

Ideally, I would like to have the Android Gmail app like the iOS app... Thanks in advance.
