Return 0 Or 1 From Multiple Inputs With Same Name

I have a table with a bunch of inputs. The user can enter data for the inputs in each row, as well as add a row, move a row, delete a row. The names for the inputs in each column are column1[], column2[], etc. I use PHP to receive the form, and the inputs are automatically converted into arrays. Every thing works great until now....

I want to add a new column with a simple yes/no input.

<input type="checkbox" name="newcolumn[]" /> doesn't work because if the checkbox is not checked, it doesn't return anything and my array for this column no longer correlates with the arrays for the other columns.

<input type="radio" name="newcolumn[]" value="0" /><input type="radio" name="newcolumn[]" value="1" /> doesn't work because each row uses the same name.

Giving each row a unique name will be very difficult given how I add/remove/move rows.

My "simple" input turned out not to be very simple. how I can return a zero or one from each row of inputs?

I am thinking of using JS to upon submit, check another checkbox input (with value=0) adjacent to the first one (with value=1) for each row if the first one isn't checked.

I am also thinking of adding hidden input to each row, and giving the user some sort of button on each row which uses JS to set the hidden input to 1 or 0.
