How to add space between table rows with tailwind?

I am new to tailwind and trying to add space between table rows.

      <table className="table-auto w-full shadow-md mt-5 rounded">
        <thead className="bg-base-200 text-left text-gray-700  tracking-wider">
          <tr>
            <th className="p-4 ">Chapter Number</th>
            <th className="p-4 ">Chapter Name</th>
            <th className="p-4 ">Added at</th>
            <th className="p-4 ">Status</th>
          </tr>
        </thead>
        <tbody>
          {chapters.map((chapter) => (
              <tr className="bg-card mt-6 rounded" key={chapter.chapterNumber}>
                <td className="p-4">{chapter.chapterNumber}</td>
                <td className="p-4">{chapter.chapterName}</td>
                <td className="p-4">{chapter.addedAt}</td>
                <td className="p-4">{!chapter.published && 'Not published'}</td>
              </tr>
          ))}
        </tbody>
      </table>

This does not add space between the table rows. So,I have tried with mt-6 on each rows. It has no effect.

I have seen a similar question and used the answer here and have added border-spacing and border-seperate.

So, now my table row has these classes.

<table className="table-auto w-full shadow-md mt-5 border-spacing-2 border-separate rounded">

But this results in adding space around all the elements.

I do not understand why table row behaves this way and does not take the margin with mt-6.

But if I replace the rows with a div, it applies the margin top. eg:

      <div>
        <th className="p-4 ">Chapter Number</th>
        <th className="p-4 ">Chapter Name</th>
        <th className="p-4 ">Added at</th>
        <th className="p-4 ">Status</th>
      </div>
      <div className="mt-6 bg-card">
        <th className="p-4 ">1</th>
        <th className="p-4 ">Chapter Name</th>
        <th className="p-4 ">04/2/2022</th>
        <th className="p-4 ">Not published</th>
      </div>
      <div className="mt-6 bg-card">
        <th className="p-4 ">1</th>
        <th className="p-4 ">Chapter Name</th>
        <th className="p-4 ">04/2/2022</th>
        <th className="p-4 ">Not published</th>
      </div>

First you need to split the borders with Tailwind border-separate property on the table tag, then add border-spacing-y-3 where: y is the axis and number is the height between row.

Utilities for controlling the spacing between table borders: Tailwind documentation

    <tr>
      <th class="p-4">Chapter Number</th>
      <th class="p-4">Chapter Name</th>
      <th class="p-4">Added at</th>
      <th class="p-4">Status</th>
    </tr>
  </thead>
  <tbody class="">
    <tr class="bg-card rounded text-gray-200 bg-neutral-900">
      <td class="p-4">60001</td>
      <td class="p-4"></td>
      <td class="p-4">6/21/2022</td>
      <td class="p-4">Not published</td>
    </tr>
    <tr class="bg-card rounded text-gray-200 bg-neutral-900">
      <td class="p-4">60001</td>
      <td class="p-4"></td>
      <td class="p-4">6/21/2022</td>
      <td class="p-4">Not published</td>
    </tr>
  </tbody>
