How to scrape a table using Puppeteer?

Question

What I want is to scrape a table, and save the data in an Array like result=[tr][ts] .

How can I make the result I want?

I'm trying something like this:

const row = await mainframe.$$eval('#clasificacion > .panel > .table- responsive > #resultadosTable > tbody > tr ', trs => trs.map((tr) =>{
console.log(tr);
return tr.textContent;}));

But the result is like result=[tr] .

You can use the following method to obtain a 2D array of table cell textContent which can be accessed via row[rowNum][cellNum] :

const selector = '#clasificacion > .panel > .table-responsive > #resultadosTable > tbody > tr';

const row = await mainframe.$$eval(selector, trs => trs.map(tr => {
    const tds = [...tr.getElementsByTagName('td')];
    return tds.map(td => td.textContent);
}));

// console.log(row[rowNum][cellNum]); <-- textContent
