HTML email template Background Color issue in Outlook

My HTML-Email template background color is not rendering properly in Outlook.

I have used different techniques but still not working.

I have wrapped the whole section into a table and applied background color to #ececec and applied color to inner td background to #ffffff but still whole outer table background color is #ffffff I want the outer table background color to be #ececec as shown in Gmail view.

Gmail view:

Outlook desktop view:

How to make it same looking as in Gmail?

Here is my code

<table bgcolor="#ececec" align="center" border="0" cellspacing="0" cellpadding="0" style="width:100%; border-collapse: collapse;">
  <tr>
      <td bgcolor="#ffffff"  style="text-align: justify;width: 50%;">
        <table bgcolor="#ffffff" border="0" cellspacing="0" cellpadding="0" style="border-collapse: collapse;">
              <tr>
                  <td bgcolor="#ffffff" style="padding-left: 30px; padding-right: 10px; ">
                      <img width="40" height="40" alt="" src="https://www.example.com/pub/media/wysiwyg/icons/icon-number1.png" style="vertical-align: middle; display: inline-block; width: 40px; height: 40px;">
                  </td>
                  <td bgcolor="#ffffff" style="width: 74%; padding-top: 20px;padding-bottom: 20px;">
                      <div style="vertical-align: middle; display: inline-block;">

Solution

It looks like you're trying to do too much with one table. You have the table background set to light grey and its <td>s set to a white background. That will give you a white table that spans 100% of the viewport. You won't even see the light gray. The tds make up the table.

Try nesting more tables to pull this off. Consider this simplified structure.

<!-- body background -->
<table width="100%">
  <tr>
    <td bgcolor="#ececec" style="padding: 20px 0 20px 0;">
      
      <!-- container background-->
      <table width="500" align="center">
        <tr>
          <td bgcolor="#ffffff" style="padding: 20px 20px 20px 20px;">
            
            <!-- content -->
            <table width="100%">
              <tr>
                <td>This content has a white background. No need to set a background color for every td.</td>
              </tr>
              <tr>
                <td>This content has a white background too, just to be clear.</td>
              </tr>
            </table>

          </td>
        </tr>
      </table>

    </td>
  </tr>
</table>

Again, this HTML is simplified to demonstrate a sturdy way to have a container of one background color exist in front of another background color.
