Select n children

Select n children

Hello I need to select the two first cells in each row of a table, BUT :nth-child only allows 1 argument.

For example I tried

$('tr td:nth-child(1-2)')
$('tr td:nth-child(1,2)')
$('tr td:nth-child(<2)')
$('tr td:nth-child(:lt(2))')

But aint working. Pure :lt() selects the first two cells of the table only, so does slice(0,2)

Why is jQuery lacking such an important function, "select n children" with arguments (range, 3-8 or just 2, which equals 0,2 or 0-2)...?
