If I understood you correctly did you mean that you wanted to only place a requirement within the second row?
Yes... row 2 mandatory in each box in that row. Perfect.
The other rows can be optional.
OR even better... IF someone adds something to the C row (cost) then they must also fill in the other two columns in that row. Is that possible?
==================Also, we tested a total and the total auto came up to 39.9995 (or something like that) when two numbers were added that only went to two decimals.
Unfortunately, I'm unable to make a solution for that, it seems that it's not in the settings of the "Spreadsheet Widget" and a custom CSS to make the specific cell/row required seems not to work here. I'll ask my colleague KadeJM if the above screenshot is a working workaround for him.
You will receive an update regarding this matter. Also, I've made a separate thread regarding the two decimal concern that you have, you can check it here: http://support.jotform.com/answers/457164
