下面是嵌入HTML的JavaScript：

<!DOCTYPE html>
<html>
  <head>
    <title>JS Read CSV</title>
    <style>
      * {
        font-family: Arial, Helvetica, sans-serif;
        box-sizing: border-box;
      }
      table {
        margin: 10px;
        margin-bottom: 10px;
      }
      table {
        border-collapse: collapse;
      }
      table tr:nth-child(odd) {
        background: #f2f2f2;
      }
      table td {
        border: 1px solid #ddd;
        padding: 10px;
      }
    </style>
  </head>
  <body>
    <!-- FILE PICKER -->
    <input type="file" accept=".csv" id="picker">

    <!-- DISPLAY CSV HERE -->
    <table id="table"></table>

    <script>
      // Create a function to copy the text to clipboard
      const copyToClipboard = str => {
        const el = document.createElement("textarea");
        el.value = str;
        document.body.appendChild(el);
        el.select();
        document.execCommand("copy");
        document.body.removeChild(el);
      };

      window.onload = () => {
        // FILE READER + HTML ELEMENTS
            var reader = new FileReader(),
                picker = document.getElementById("picker"),
                table = document.getElementById("table");

            // READ CSV ON FILE PICK
            picker.onchange = ()=> reader.readAsText(picker.files[0]);

            // READ THE CSV FILE & GENERATE HTML
            reader.onloadend = () => {
                // ENTIRE CSV FILE
                let csv = reader.result;

                //CLEAR HTML TABLE 
                table.innerHTML = "";

                // SPLIT INTO ROWS
                let rows = csv.split("\r\n");

                // LOOP THROUGH ROWS + SPLIT COLUMNS 
                for (let row of rows) {
                let cols = row.match(/(?:\"([^\"]*(?:\"\"[^\"]*)*)\")|([^\",]+)/g);
                if (cols != null) {
                    let tr = table.insertRow();
                    for (let col of cols) {
                    let td = tr.insertCell();
                    td.innerHTML = col.replace(/(^"|"$)/g, "");
                    }
                }
            }
        };
    };
    </script>
</body>

我想在第2列的行中添加超链接。当您单击超链接文本时，我想让JavaScript将链接复制到剪贴板。
我发现下面的JavaScript在Click on text to copy a link to the clipboard，但我不知道如何添加到上述JavaScript嵌入HTML.
x一个一个一个一个x一个一个二个x
CSV文件如下所示：

# No, Position, Duration, Comment
1,"00:02:09:120","00:00:03:000","Hello"
2,"00:10:45:559","00:00:03:000","Goodbye"
