[jQuery] [Tablesorter] Looping through headers object


Hi everybody.
I have an html table with a fixed number columns (or headers) and a
variable number of columns, that may vary in numbers depending on data
in the DB.
I want to make sortable one or two columns of the fixed ones, so I
would like to know how to loop through the headers object in order to
set to "sorter:false" all the headers that I want to be UN-sortable.
In other words, something like:
for(i=0;i<colNum;i++) {
if(i != x) {
headers: { i: {sorter: false} }
}
}
where x is the index I want to be sortable.
Sorry for my stupid question, but me and javascript aren't good
friends :(
Thanks in advance for any answer.
