Hide and Replace Div after a certain time

Question

I am displaying a table in angular on the components html component. I noticed that the pull of the data and filtering the data takes some time and the table doesn't load right away. so I decided to add a loading spinner image however I want the loading spinner to disappear after about 5 secs and for the table to appear. I wrote some code to have the spinner disappear after 5 secs however I am running into the trouble of the loading spinner div still being on the page and having to scroll down to see the table in the overflow box. is there a way to make the loading spinner div complete disappear or maybe even swap the table div for the spinner div?

component.html

<!-- Displaying Data from NCEI Data Pull -->
<h1>Preview Data</h1>
<div id="scrollable-area">
    
    <!-- Display Loading Circle -->
    <div class="loading hide">
        <div class="circle"></div>
    </div>

    <table class="table">
    
        

        <!-- Display Headers -->
        <th *ngFor = "let row of headers">
            {{row}}
        </th>
    
        <!-- Display Data -->
        <tr *ngFor = "let row of dataObj">
            <td *ngFor = "let column of row" class="rows">{{ column }}</td>
        </tr>
    </table>
</div>

}

any advice would be appreciated.
