'Spacing between table rows in Dreamweaver mail template

I tried some solutions I found in other posts but still no luck. I'm getting a small spacing between all my table rows. All CSS and HTML seems in order. Any ideas?

table {
    border-spacing: 0 !important;
    border-collapse: collapse !important;
    table-layout: fixed !important;
    margin: 0 auto !important;


<table cellpadding="0" cellspacing="0" border="0" height="100%" width="100%" bgcolor="#e0e0e0" 
style="border-collapse:collapse;">

Please change border-collapse:collapse; to border-collapse:separate; into your table tag inline style.

And use the below CSS code.

table {
    border-collapse: separate;
    border-spacing: 0 1em;
}
<table border="1" style="border-collapse:separate; margin:0 auto;" cellspacing="5" cellpadding="5">
<tr>
    <th>Heading 1</th>
    <th>Heading 2</th>
</tr>
<tr>
    <td>Value 1</td>
    <td>value 2</td>
</tr>
<tr>
    <td>Value 3</td>
    <td>value 4</td>
</tr>
<tr>
    <td>Value 5</td>
    <td>value 6</td>
</tr>
</table>
