You will need to check the structure of all the tables. Each table with open with a <table> tag. Most tables will then have a <caption> tag located after the opening tag.

Within the table there will be two main sections:

1. <thead> section, where the info for the table header row is found.
2. <tbody> section, where the rows containing all the table data are found.

Each new row of a table should be within a <tr> tag. The Header Row will have a <th> tag for each item. The Body Rows will have a <td> tag for each item.

All tables should follow a similar structure as shown below.

<table>
     <caption>Title of Table</caption>
     <thead>
            <tr>
                <th>Number</th>
                <th>Letter</th>
                <th>Colour</th>
            </tr>
     </thead>
     <tbody>
             <tr>
                 <td>1</td>
                 <td>2</td>
                 <td>3</td>
             </tr>
             <tr>
                 <td>A</td>
                 <td>B</td>
                 <td>C</td>
             </tr>
             <tr>
                 <td>Blue</td>
                 <td>Green</td>
                 <td>Red</td>
             </tr>
     </tbody>
</table>
