Answer №1

I made some updates to the content: I apologize for missing the scrolling issue. Please utilize flex-direction: column in DataTable.js

  tableContent: {
    overflowY: "scroll",
    borderCollapse: "collapse",
    display: "flex",
    flexDirection: "column"
  },

Also, adjust the width of the table head cells to 10%:

 tableCellHead: {
    fontSize: "1rem",
    fontWeight: "bold",
    border: "1px solid rgba(224, 224, 224, 1)",
    width:" 10%",
    "&:last-child": {
      paddingRight: "4px"
    }
  },

Issue with Table Header and Body Alignment

The misalignment of your table header and body is a result of the display: flex property being used in both the .DataTable-tableContent-4 CSS class of your <table> element and in the inline style of your <tbody>. Removing this property will resolve the alignment issue.

Fixing Scrollability of Your Table

To make your table scrollable, you correctly set the height and overflow-y: scroll, but they should be applied to a parent container of the table, not directly on the table itself.

Making the Table Header Stick While Scrolling

By using the position: sticky attribute with a top: 0 value, you can ensure that your table header remains fixed at the top while scrolling.

Check out this code snippet for demonstration:

.container {
  height: 150px;
  overflow-y: scroll;
}

thead {
  position: sticky;
  top: 0;
  z-index: 100;
  background-color: #fff;
}
<div class="container">
  <table>
    <thead>
      <tr>
        <td>Name</td>
        <td>Reputation</td>
        <td>Meme potential</td>
      </tr>
    </thead>
    <tbody>
      <!-- Table data here -->
    </tbody>
  </table>
</div>
