var set = [];
$('table tr').each(function() {
    var row = [];
    
    $(this).find('td').each(function() {
        row.push($(this).text());
    });
    
    set.push(row);
});

In this way, all the td items in the entire table will be stored in a two-dimensional array set in order from row to column, similar to the structure below

[
    [列1, 列2, ...], // 行1
    [列1, 列2, ...], // 行2
    ...
]
