How to make tr's box-shadow overlap the next tr in the table?

Question

css

Hello.
In general, there is a table:

<table>
            <thead>
                <tr>
                    <th>One</th>
                    <th>Two</th>
                    <th>Three</th>
                    <th>Four</th>
                    <th>Five</th>
                    <th>Six</th>
                    <th>Seven</th>
                </tr>
            </thead>
            <tbody>
                <tr>
                    <td>1</td>
                    <td>2</td>
                    <td>3</td>
                    <td>4</td>
                    <td>5</td>
                    <td>6</td>
                    <td>7</td>
                </tr>
                <tr>
                    <td>1</td>
                    <td>2</td>
                    <td>3</td>
                    <td>4</td>
                    <td>5</td>
                    <td>6</td>
                    <td>7</td>
                </tr>
                <tr>
                    <td>1</td>
                    <td>2</td>
                    <td>3</td>
                    <td>4</td>
                    <td>5</td>
                    <td>6</td>
                    <td>7</td>
                </tr>
                <tr>
                    <td>1</td>
                    <td>2</td>
                    <td>3</td>
                    <td>4</td>
                    <td>5</td>
                    <td>6</td>
                    <td>7</td>
                </tr>
        </tbody>
    </table>

body {
    margin: 0;
    background: #eee;
}

table {
    width: calc(100% - 40px);
    margin: 40px 20px;
    border-collapse: separate;
    border-spacing: 0 10px;
}

table tbody tr {
    cursor: pointer;
    border-radius: 10px;
}

table tbody tr:hover {
    box-shadow: 0 12px 10px 0 rgba(0,0,0,0.15);
}

table tbody tr td {
    background-color: #fff;
    padding: 10px 20px;
}

table tbody tr > td:first-child {
    border-radius: 10px 0 0 10px;
}

table tbody tr > td:last-child {
    border-radius: 0 10px 10px 0;
}

When you hover over a line, a shadow appears that hides behind the next line. And I need it to be on top of the next line. Please help me solve the problem.
Thanks in advance.

You need to add z-index:
