Why won't this code on sololearn work and how do I make it work?

Question

On sololearn I was given this code:
<table>
<tr>
<td>
<td>
<td>
</tr>
</table>
Which is supposedly suppose to make a table with one row and three columns but when I typed it in on sololearn's online IDE it output anything and I don't understand why. Unless I've done something wrong how do I make it work?

Answer 1

Try adding some input to the table data td then close each with </td>
<td>1</td>...

Answer 2

I guess you forgot to close the <td>.
<table>
<tr>
<td> info1 </td>
<td> info2 </td>
<td> info3 </td>
</tr>
</table >

Answer 3

after opening the <td> tags you forgot to close them try that.
