How can I add rows <tr> in to a table a any level(Top/Bottom/开发者_如何学GoIn between) using Javascript/jQuery ?

---

$(html).insertBefore($('table tr').eq(index));

Will insert some html before the tr with index specified.

A small demo

• to append to the bottom:

you have nothing to do, because you just have to find the parent element and then append it.

• to append to the top:

well, it is more complicated, but I think is possible. One way is following:

find the parent element from the rows and read all rows into an extra variable. Fortunatly the result will be an array of object. Then create a new row element and use the method unshift() to put this at the begin of the array. Clean table's body and then add each element to body again.
