cheerio scarp entire table

I try to scrape the entire table by NodeJS+CheerioJS which has structure like this

<table class="table table-hover table-info">
        <caption></caption>
        <thead>      // 1 <tr> 
        </thead>
        <tbody>      // 12 <tr>
        </tbody>
        <thead>     // 1 <tr>
        </thead>
        <tbody>     // 7 <tr>
        </tbody>
</table>

that webpage has only 1 table with 2 thead and 2 tbody

what I had tried is

$('table').filter(function(){
        var data = $(this);
        console.log(data.find('thead').length)    // print '2'
        console.log(data.find('tbody').length)    // should print '2' but it print '1'
        console.log(data.find('tr').length)    // should print '21' but it print '14'
})

the result should be 2, 2 and 21 but it returned me 2, 1 and 14

any idea how to get the second tbody ?

p.s. I also tried

$('table.table.table-hover.table-info').filter(function(){
        // same code
})

it still return 2,1,14 :/

Thank you
