here is my sample code.
<table id="sampleTable" class="table table-striped table-bordered">
<thead>
<tr>
<th>th1</th>
<th>th2</th>
<th>th3</th>
</tr>
</thead>
<tbody>
<tr style="cursor:pointer"> <!-- I want to click this row -->
<td> text1</td> <!-- when the row is clicked, I want to change this text "text1" to "<input>" tag. -->
<td> text2</td>
<td> text3</td>
</tr>
</tbody>
</table>
there aren't any thymeleaf tag, but I can use them whem I want to.
Here you go with the solution https://jsfiddle.net/8h00oc9d/1/
$('table tbody tr').click(function(){
$($(this).children()[0]).html('<input type="text" />')
});

<table id="sampleTable" class="table table-striped table-bordered">
<thead>
<tr>
<th>th1</th>
<th>th2</th>
<th>th3</th>
</tr>
</thead>
<tbody>
<tr style="cursor:pointer"> <!-- I want to click this row -->
<td> text1</td> <!-- when the row is clicked, I want to change this text "text1" to "<input>" tag. -->
<td> text2</td>
<td> text3</td>
</tr>
</tbody>
</table>
