Dirask - sort cross technology table

Quick solution:

(function sort(columnIndex) {
    //const table = document.querySelector('table');
    const table = document.querySelector('.cke_wysiwyg_frame')
                .contentWindow.document.querySelector('table');

    const rows = table.rows;

    outer:
    while (true) {
        for (let index = 1; index < rows.length - 1; index++) {
            const row1 = rows[index];
            const row2 = rows[index + 1];

            const text1 = row1.cells[columnIndex].innerText.toLowerCase();
            const text2 = row2.cells[columnIndex].innerText.toLowerCase();

            if (text1 > text2) {
                row1.parentNode.insertBefore(row2, row1);
                continue outer;
            }
        }
        break;
    }
})(0);
