Table cells not even

I have created a child theme for twenty sixteen and I want organize my content using a table. I have a simple table, and I don’t understand what in the parent style.css that could be causing the 3rd cell to not be the same size as the 1st. I’ve done html coding in the past, using plenty tables, and nested. I put this same code in a straight html doc and it is all even. Is there a simple fix?
My table code (in Edit Page of WP)

<table bgcolor="#262262" width="1000">
<tr>
<td width="250">
<img src="http://www.dionescastro.com/wp-content/uploads/2016/08/Page-EventsPageImage.png" alt="Our Events" width="250" height="800" />
</td>

<td width="20"></br></td>

<td style="text-align: justify;" valign="top" bgcolor="FFFFFF">
</br>
</td>
</tr>
</table>

style code related to tables

table,
th,
td {
	border: 0px solid #d1d1d1;
}

table {
	border-collapse: separate;
	border-spacing: 0;
	border-width: 0px 0 0 0px;

	table-layout: fixed;
	/* Prevents HTML tables from becoming too wide */
	width: 100%;
}

caption,
th,
td {
	font-weight: normal;
	text-align: left;
}

th {
	border-width: 0 1px 1px 0;
	font-weight: 700;
}

td {
	border-width: 0 0px 0px 0;
}

th,
td {
	padding: 0.4375em;
}

I see some
“body:not(.search-results) .entry-summary table {
margin-bottom: 1.4736842105em;”
code in the style.css …would these lines be contributing at all?
Yes, I certainly have some learning to do with regards to WP and PHP coding. I am self taught html and feeling my way around WP. Thanks in advance.
