Within each of your new th elements, nest a span element with the class set to sr-only year. Give them the following text (in order): 2019, 2020, and 2021.
Give your third th element the class attribute set to current.
Leave the td element empty. This element exists only to ensure your table has a four-column layout and associate the headers with the correct columns.
Each of your th elements should have a span element.
const ths = [...document.querySelectorAll('th')];
ths?.forEach(th => {
assert(th?.children?.length === 1);
assert(th?.children?.[0]?.localName === 'span');
});
Each of your new span elements should have the class attribute set to sr-only year.
const ths = [...document.querySelectorAll('th')];
ths?.forEach(th => {
assert(th?.children?.[0]?.classList?.contains('sr-only'));
assert(th?.children?.[0]?.classList?.contains('year'));
});
Your first span element should have the text 2019.
assert(document.querySelectorAll('th')?.[0]?.children?.[0]?.textContent === '2019');
Your second span element should have the text 2020.
assert(document.querySelectorAll('th')?.[1]?.children?.[0]?.textContent === '2020');
Your third span element should have the text 2021.
assert(document.querySelectorAll('th')?.[2]?.children?.[0]?.textContent === '2021');
Your third th element should have the class set to current.
assert(document.querySelector('table')?.querySelectorAll('th')?.[2]?.classList?.contains('current'));
Your td element should be empty.
assert(document.querySelector('table')?.querySelectorAll('td')?.[0]?.textContent === '');
assert(document.querySelector('table')?.querySelectorAll('td')?.[0]?.children?.length === 0);
