how would you deal with a DataTable value that is too long?

In the case of a long value that makes the column too wide, I am probably expecting the value to be truncated and displaying the whole value in a tooltip on hover, but I could not achieve a good result with the provided tooltip components. Any tips?

@halindraprakoso an alternative you may consider is having your contents wrap. You can achieve this by setting a width key in your respective column heading:

<script>
  import { DataTable } from "carbon-components-svelte";
</script>

<DataTable
  headers={[
    { key: "name", value: "Name" },
    { key: "protocol", value: "Protocol", width: "20ch" }, /* custom width */
    { key: "port", value: "Port" },
    { key: "rule", value: "Rule" },
  ]}
  rows={[
    {
      id: "a",
      name: "Load Balancer 3",
      protocol: "HTTP",
      port: 3000,
      rule: "Round robin",
    }
  ]}
/>

If you want to truncate your copy, then perhaps using slotted cells you could have the text truncate with CSS and provide a button for the user to expand its contents inline; that way a screen reader can still read the copy and sighted users still have a means of reading the full text.
