Get value from HTML Table Cell
Question
I want a HTML Table in such a way that I can select only one cell and retrieve it's value so I can use in other operations on my app. The problem is that I have no idea on how to structure the table in a way that only one cell can be selected, the selected cell change it's color and so on. Here's an example so you guys can picture what I have in mind.
And here is the hardcoded model of my app:
<body>

give an id and use getElementById() to select the cell. Don't use the center tag, its depricated. I am assuming you want to use javascript

try like this. i am giving the value in alert. you can just assign the value in a variable and use in your app. the html table is full yours one, i just added an id to the table. and a css class 'active' to hightlight the click div. (you need to include the jquery script in you page)
$(document).ready(function(){ $(document).on('click','.mytable tbody tr td',function(){ $(this).addClass('active'); $(this).parents('tbody').find('td').not(this).removeClass('active'); alert($(this).find('strong').html()); }); });
.active{ background: #999; }
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <table id="" border='1' class="mytable w3-table-all w3-card-4" style="width: 100%"> <tbody> <tr> <td> <center> Casa<br> <strong>2.00</strong> </center> </td> <td> <center> Casa<br> <strong>2.00</strong> </center> </td> <td> <center> Casa<br> <strong>2.00</strong> </center> </td> </tr> <tr> <td> <center> Casa<br> <strong>2.00</strong> </center> </td> <td> <center> Casa<br> <strong>2.00</strong> </center> </td> <td> <center> Casa<br> <strong>2.00</strong> </center> </td> </tr> <tr> <td> <center> Casa<br> <strong>2.00</strong> </center> </td> <td> <center> Casa<br> <strong>2.00</strong> </center> </td> <td> <center> Casa<br> <strong>2.00</strong> </center> </td> </tr> </tbody> </table>

If you have
<td id="cell1"></td>
then in jQuery
$(function() { //this wrapper just tells the script not to run until the whole page is rendered
$("#cell1").click(function(event) { //this bit handles any user clicks on cell1
console.log("clicked cell 1");
});
});
will log to the browser console whenever the user clicks it.
If you want to run the same event for multiple cells then give them all a class and select against that instead (eg <td class="myGroup"> and $(".myGroup").click(... ).
This all uses standard jQuery syntax for binding to browser events - might be worth reading up on the basics of this.

This answer assumes you're looking to get values from the table by clicking on table cells.
For jQuery I would use a delegated approach to adding a click handler to all cells of the table. By using a delegated approach you are attaching fewer click handlers to the page and it will also work if you dynamically add cells to the table at a later time (ie Ajax).
Click on table cells in the Code Snippet to see their value copied to the green box.
var $display = $('.display'); $('.my-table').on('click', 'td', function(e) { $display.text(this.innerHTML); });
.display { width: 200px; margin: 1rem 0; padding: 0.5rem 1rem; border: 1px solid green; }
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <table class="my-table"> <tr> <th>First Name</th> <th>Last Name</th> <th>Age</th> </tr> <tr> <td>Aaron</td> <td>Anderson</td> <td>1</td> </tr> <tr> <td>Beth</td> <td>Black</td> <td>2</td> </tr> </table> <div class="display"></div>
Note: As others have noted, the <center> tag is depreciated . Use text-align instead.

$("#cell1").click(function(){
$(this).css("background-color", "#ccc");
});
