How to get the td that contains tr with a button that has a specific attribute?

I'm trying to get all the tds in a table that contain a tr with a button to which I have specified an attribute ("boolean") with a true or false value. I need to get each td that have that attribute with value true but I can't figure out how to get it using jquery.
The structure would be the following:
<table id="table">
<thead>
</thead>
<tbody>
<tr row-id="1">
<td class="text-left">
<div />
</td>
<td class="text-left td-button">
<button boolean="true">Button</button>
</td>
</tr>
<tr row-id="2">
<td class="text-left">
<div />
</td>
<td class="text-left td-button">
<button boolean="false">Button</button>
</td>
</tr>
<tr row-id="3">
<td class="text-left">
<div />
</td>
<td class="text-left td-button">
<button boolean="true">Button</button>
</td>
</tr>
</tbody>
</table>
I have tried to do something like this:
function colour() {
$("#table tbody tr").each(function() {
let colour = $(this).children("td")[1];
}
}
But I can't go from there to get those td since I have no experience with jquery
How could I get the td with row-id 1 and 3 with Jquery and then apply a style to those td?
Thanks in advance

Use a has selector with attribute selector
var trs = $('tr:has(button[boolean="true"])');
console.log(trs);
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<table id="table">
<thead>
</thead>
<tbody>
<tr row-id="1">
<td class="text-left">
<div />
</td>
<td class="text-left td-button">
<button boolean="true">Button</button>
</td>
</tr>
<tr row-id="2">
<td class="text-left">
<div />
</td>
<td class="text-left td-button">
<button boolean="false">Button</button>
</td>
</tr>
<tr row-id="3">
<td class="text-left">
<div />
</td>
<td class="text-left td-button">
<button boolean="true">Button</button>
</td>
</tr>
</tbody>
</table>

$("#table tbody tr").each(function() {
//Filter to iterate those td's which contain Boolean true
if($(this).find('button').attr('boolean')=="true"){
let colour = $(this).children("td")[1];
colour.style.backgroundColor="red";
console.log(colour);
}
})

Dynamically lock tr at bottom of table

is there some way to lock a tr at the end of a table with VUE or Js?
I have a Vue-Component which adds tablerows dynamically based on an API call, but I need one specific tr to be at the bottom and if a new tr is added, it should be above the last one.
Not in the tfoot because there is some other nformation
Here is the Vue-Component
<tbody>
<tr is="deliverytable"
v-for="delivery in deliveries"
v-bind:key="delivery.id"
v-bind:delivery="delivery"></tr>
</tbody>
Template of the Vue-Component
<tr id="data" :class="{'incomplete' : delivery.event == '4'}">
<td>
<div v-if="delivery.is_printable">
<input name="deliverynote" :value="delivery.id" :checked="delivery.is_printable_by_default" type="checkbox">
</div>
</td>
<td>[[ delivery.dispatched ]] Uhr</td>
<td>[[ delivery.action ]]</td>
<td>
<div v-if="!delivery.is_deletable">[[ delivery.article_name ]]</div>
<div v-else-if="delivery.event != 0" v-on:change.close="autosave($event, delivery.id)" ref="article" v-html="delivery.articleform"></div>
</td>
<td>
<div v-if="!delivery.is_deletable">[[ delivery.amount ]]</div>
<div v-else-if="delivery.event != 0" #change="autosave($event, delivery.id)" ref="amount" v-html="delivery.amountform"></div>
</td>
<td><div id="weight" ref="delivery">[[delivery.weight]]</div></td>
<td class="d-none"><input type="text" name="delivery" id="id_delivery" :value="delivery.id">[[delivery.id]]</td>
<td id="price" ref="price">[[ delivery.price ]]</td><td v-else>0.00 €</td>
<td>
<a v-if="delivery.is_deletable" type="button" #click="removeDelivery(delivery.id)" class="icon icon-trash-can"></a>
</td>
</tr>

If your components iterated over in a loop you can render this specific after loop above
<table>
<thead>
some headers
</thead>
<tbody>
<tr v-for="(rowItem, key, index) in dataTable" :key="index">
your API call items
</tr>
<tr>
your specific item
</tr>
</tbody>
</table>

The above is just an example of a row from my table.
Upon appending $(this).closest("tr").after("<tr><td colspan='2'></td><td colspan='9'>" + $(this).next().html() + "</td></tr>"); on a button click the table becomes visible in the new <tr>
To my extend my knowledge , apparently it's been appended directly to tr since the display is set to none, does the dom elements work like this ?
I'm novice at the most, when it comes to html.
Can Anyone please explain why this happens ?
Any relevant information will greatly appreciated.

Your selection (using html()) returns the contents of the element, not the element itself, so any attributes on the element are also disregarded. One easy fix might be to move your hide styles down a level:
<div id="data_hidden">
<table style="display:none">
<tr>
<td>
Hidden data appears
</td>
</tr>
</table>
</div>
Demo 1
This leaves the original div element in the DOM, but it doesn't affect appearance.
Alternatively, grab the outerHTML of the selection's raw element:
$(this).closest("tr").after("<tr><td colspan='2'></td><td colspan='7'>"
+ $(this).next().get(0).outerHTML + "</td></tr>");
});
Demo 2

index class in different rows in jquery

I have a table with buttons on each row. I am trying to click on a button on a particular and it picks the value .claim_value field of the same row and put the value in the td opposite it .vet_value.
Here's my code
<table id="tasks" class="col-md-12 table">
<thead>
<tr>
<td>Service</td>
<td>Key notes</td>
<td>Claim Amount</td>
<td>Vetted Amount</td>
</tr>
</thead>
<tbody>
<tr class="therow">
<td class="claim_value">hey</td>
<td class="vet_value"></td>
<button class="button">button</button>
</tr>
<tr class="therow">
<td class="claim_value">you</td>
<td class="vet_value"></td>
<button class="button">button</button>
</tr>
<tr class="therow">
<td class="claim_value">me</td>
<td class="vet_value"></td>
<button class="button">button</button>
</tr>
<tr class="therow">
<td class="claim_value">them</td>
<td class="vet_value"></td>
<button class="button">button</button>
</tr>
</tbody>
</table>
so i want to be able to click on class="button"
$(".button").click(function(){
(".claim_value").val() of this same row goes into (".vet_value").val()
});

Just call parent() to access the parent <tr> element and modify <td> from there
$(".button").click(function(){
var $parent=$(this).parent();
var claimValue=$parent.find(".claim_value").text();
$parent.find(".vet_value").text(claimValue);
});

you don't need to use .val() unless the element is input or textarea
with td use .text() also you need to use $(this) to refer to the button you clicked and closest('tr') to select the closest row then .find() to find the element with class you want
$(".button").click(function(){
var claim_value = $(this).closest('tr').find(".claim_value").text();
$(this).closest('tr').find(".vet_value").text(claim_value);
});

Use html() that is not val(). Insert td inside which has to be the direct child of tr. As val() only comes for input and textarea.
$(".button").click(function(){
alert($(this).closest('tr').find(".claim_value").html());
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<table id="tasks" class="col-md-12 table">
<thead>
<tr>
<td>Service</td>
<td>Key notes</td>
<td>Claim Amount</td>
<td>Vetted Amount</td>
</tr>
</thead>
<tbody>
<tr class="therow">
<td class="claim_value">hey</td>
<td class="vet_value"></td>
<td>
<button class="button">button</button>
</td>
</tr>
<tr class="therow">
<td class="claim_value">you</td>
<td class="vet_value"></td>
<td>
<button class="button">button</button>
</td>
</tr>
<tr class="therow">
<td class="claim_value">me</td>
<td class="vet_value"></td>
<td>
<button class="button">button</button>
</td>
</tr>
<tr class="therow">
<td class="claim_value">them</td>
<td class="vet_value"></td>
<td>
<button class="button">button</button>
</td>
</tr>

jQuery - toggle button show/hide table data

I'd like some help please.
<h2>Operating systems <span class="button small toggle-btn">Toggle</span></h2>
<table class="data" cellpadding="8" border="1">
<thead>
<tr>
<th class="first" style="width:120px">
Operating System </th>
<th class="">
Percentage </th>
</tr>
</thead>
<tbody>
<tr>
<td class="">iOS 8.4</td>
<td class="">
<div class="ui-percentage" style="width:17%">17 %</div>
</td>
</tr>
<tr class="tr even">
<td class="">iOS 8.3</td>
<td class="">
<div class="ui-percentage" style="width:6%">6 %</div>
</td>
</tr>
<tr>
<td class="">iOS 8.2</td>
<td class="">
<div class="ui-percentage" style="width:11%">11 %</div>
</td>
</tr>
<tr class="tr even">
<td class="">iOS 8.1.3</td>
<td class="">
<div class="ui-percentage" style="width:11%">11 %</div>
</td>
</tr>
<tr>
<td class="">iOS 8.1</td>
<td class="">
<div class="ui-percentage" style="width:6%">6 %</div>
</td>
</tr>
</tbody>
</table>
When the page loads for the first time I want the table to be collapsed. When I click the Toggle button I want to change the table status, so basically to expand it and collapse it again if the button is clicked again.
This is my script
<script>
$(document).ready(function() {
$('.toggle-btn').closest('table').hide(); // I want to target the table right after the button
$('.toggle-btn').on('click', function(event) {
$(this).closest('table').toggle();
});
});
</script>
How can I make this work correct ?

why not just use toggle function directly?
$(document).ready(function() {
$('table').hide();
$('.toggle-btn').on('click', function() {
$('table').toggle();
});
});

if you have only one table then only do
$(document).ready(function() {
$('tbody').closest('h2').next().find("tbody").hide();
$('.toggle-btn').on('click', function() {
$('tbody').toggle();
});
});
For more then one sibling tables
You can find closest h2 and next() gives you table
$(document).ready(function() {
$('.toggle-btn').closest('h2').next().find("tbody").hide();
$('.toggle-btn').on('click', function() {
$(this).closest('h2').next().find("tbody").toggle();
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<h2>Operating systems <span class="button small toggle-btn">Toggle</span></h2>
<table class="data" cellpadding="8" border="1">
<thead>
<tr>

</tr>
<tr class="tr even">
<td class="">iOS 8.1.3</td>
<td class="">
<div class="ui-percentage" style="width:11%">11 %</div>
</td>
</tr>
<tr>
<td class="">iOS 8.1</td>
<td class="">
<div class="ui-percentage" style="width:6%">6 %</div>
</td>
</tr>
</tbody>
</table>

$(document).ready(function() {
$('.toggle-btn').parent().next('table').hide(); // I want to target the table right after the button
$('.toggle-btn').on('click', function(event) {
$(this).parent().siblings('table').toggle();
});
});
Selector should be $('.toggle-btn').parent().next('table')
DEMO

the function closest() goes up the element's parents, so it will never find the table. You would have to do something like this:
$(document).ready(function() {
$('.toggle-btn').parent().parent().find('table').hide(); // I want to target the table right after the button
$('.toggle-btn').on('click', function(event) {
$(this).parent().parent().find('table').toggle();
});
});
But this would not work if there are multiple tables. Consider using an id or for the table, so that you can access it directly. Eg:
<table id="data-table-1" class="data" cellpadding="8" border="1">
That would make the javascript much simpler, ie:
$('.toggle-btn').on('click', function(event) {
$('#data-table-1').toggle();
});
