how to ForEach through ["name"] cells?

I have table in way of:
Code: Select all
mytable = {
["cella"] = { itema = 1, itemb=2},
["cellb"] = { itema = 1, itemb=2],
...
}
What I am trying is following:
Code: Select all
ForEach(mytable, Function (cell, data)
data.itema=0
EndFunction)
By otherwords, I am trying to make every cells "itema" become 0.
But how do i crawl through every cell made this way?
wether i use cell.itema, or data.itema, neither works.
I also tried mytable[cell].itema, but that didnt work either.
So is there any way to access this through ForEach, or is there some other way to do this?

Hello Bugala,
here it is using ForEach (your attempt seems correct to me):
Code: Select all
ForEach(mytable, Function(i, v) v.itema=0 EndFunction)
and using generic For
Code: Select all
For i, v In Pairs(mytable)
v.itema = 0
Next
I've tried both methods and works

Hmm. You are right. That piece of code does work right...
Have to figure out why does it sometimes work and sometimes it keeps complaining of " Wrong data types for concatenation!"
Another thing that I am wondering considering this.
That say I have a table:
Code: Select all
mytable = { x=1, y=2,
["cell1"] = {1, 2, 3},
["cell2"] = [4, 5, 6],
...
}
Now is there any possiblity to use ForEach (or something similar) in such way, that it would only go through those ["cell1"], ["cell2"] subtables, and would simply skip x and y?
I know there is ForEachI-command, but that does exactly opposite of what I looking for.

Thanks to you pointing out that the example code worked, I was able to inspect more and was able to find solution.
When using ForEach command with FUNCTION (cell, data), before doing anything else, I first use GetType command to see that it is a table. If it is, then proceed to IF part of code.
This way I was able to go through only ["cella"], ["cellb"] kind of subtables, as long as i didnt have any other subtables there that werent supposed to be checked.
