Copy table row and copy data from table column

Copy table row and copy data from table column

Hi,

I have poblem with some jquery code, can any one help me?

My html code in http://jsfiddle.net/6Uv22/

I have couple of question.
1) I want copy blank  tr row only if I write min one letter in last row. If I filled third row, I want new tr row as a fourth row. Only Name column are checked if is filled.

2) I want to show copy button. Copy button must be in between row (between first row and second row, second row and third row, and so on) and one button to copy all row. So if I have third row, I want to button to copy all data from second row and another button to copy from all column from second row. Button to copy name column, second button to copy category column and so on

3) I want to copy max ten row. When I filling ten row I want to show message.
"No more row"
Oh I forgot. Last question, I want to fill color  in tr row which is in use.

Please, help me. Thx
