Fixed Column on HTML Table with Vue JS - vue.js

Question

I'm having a problem with my table when I scroll to the right
this is my code
TableComponent.vue
<div id="main-container">
<table class="maint-table">
<thead id="table-header">
<tr>
<th class="dates"> </th>
<th v-for="data in dateHeader">{{data}}</th>
</tr>
<tr>
<th class="title"> </th>
<th v-for="data in dayOfWeek">{{data}}</th>
</tr>
</thead>
<tbody id="table-body" #scroll="fixedScroll">
<table_block :table_data="dataHeader"></table_block>
<table_block :table_data="allData"></table_block>
</tbody>
</table>
</div>
...
...
...
<script>
components: {
table_block
},
methods: {
fixedScroll() {
fixedScroll(event) {
var thead = document.getElementById("table-header");
var tbodyScroll = document.getElementById("table-body").scrollLeft;
thead.scrollLeft = tbodyScroll;
}
</script>
I made a props to pass the data to my TableBlock to loop through the data and display it on the table. This is my TableBlock Code.
TableBlock.vue
<template>
<div>
<tr v-for="row in table_data">
<td>
<div class="drop-down-container"><span class="drop-down-controller"">{{ row.title }}</span></div>
</td>
<td v-for="cel in row.data" class="group-header">{{ cel }}</td>
</tr>
</div>
</template>
When I scroll it to the right, the first column must freeze but it's not.
I tried to create a dummy data inside TableComponent.vue with a normal HTML Table without passing the data to another component using props, it works perfectly. But when I use these codes, it doesn't work correctly.
Scenario
Let say I have 10 columns in the table, when I scroll it to the right, the 1st column will stick which is normal but when the 10th column reach to 1st column, the 1st column will scroll away together with the 10th column.
I'm trying my best to illustrate the scenario but this is the best that I can do. If someone can help, please help me.
