How to make two columns same height - Zurb INK

I have two columns, one have more content = is bigger, but I want that black one to be same height like that on the right.

enter image description here

There is workaround that you add div around table width height 100% and display: inline-block, but it is an ugly hack.

Anyone know solution?

<table class="body">
        <tr>
            <td class="center" align="center" valign="top">
        <center>

            <table class="container">
              <tr>
                <td>

                <table class="row">
                  <tr>
                    <td class="wrapper">

                      <table class="six columns" style="background-color: black; color: white;">
                        <tr>
                          <td align="center" style="vertical-align: middle;">
                            <center style="vertical-align: middle; color:white;">
                              TEXT
                            </center>
                          </td>
                          <td class="expander"></td>
                        </tr>

                    <td class="wrapper last">

                      <table class="six columns" style="background-color: lightgray; color: white;">
                        <tr>

Solution

CSS class is what you need. If you are just wanting the tables to be the same height just set the height for them both as the same. either in-line or in a much easier way to manage is as a class applied to them both as below. I also added your in-line code as css as its a far better approach.

    <html>
<head>
<style type="text/css">
.tableHeight{
  height: 500px;

}

#lefttable{
  background-color: black;
  color: white;"

}

#rightTable{
  background-color: lightgray;
  color: white;
}

</style>

</head>
<body>
<table class="body">
        <tr>
            <td class="center" align="center" valign="top">
        <center>

            <table class="container">
              <tr>
                <td>

                <table class="row">
                  <tr>
                    <td class="wrapper">

                      <table id="leftTable" class="six columns tableHeight">
                        <tr>
                          <td align="center" style="vertical-align: middle;">
                            <center style="vertical-align: middle; color:white;">
                              TEXT
                            </center>
                          </td>
                          <td class="expander"></td>
                        </tr>
                      </table>

                    </td>

                    <td class="wrapper last">

                      <table id="rightTable" class="six columns tableHeight">
                        <tr>
                          <td align="center">
                            <center>
                                TEXT</br />
                                TEXT</br />
                                TEXT</br />
                                TEXT</br />
                                TEXT</br />
