How to change layout options

Hi Folks, I am sorry to bother you.

I have to questions.

1. Question 1

If I have a row with colums in them, and add ons in the colums, is there a way can change the columm lay out with out loosing everything.

so if I have

4+4+4 in a row and then I wanted to add another column

4+4+4+12+12 for example

I do not want to loose what I have i nthe first row (4+4+4) I just to add more content below it.

Question 2

2. When I add two rows to a lay out, I get a big gap between the rows, I have not been able to find where this can be controlled.

I tried to upload a pic for you to see the problem but I cannot using this form.

Here is a link to the article where you can see the issue:
