Problem In Integrating 3 Internal Tables to make data for email attachment

Question

Hi All,
I am facing a problem. I am having some data in 3 internal tables. Consider it Header Data, Details Data, Tail Data in 3 different Internal tables with different Fields.
Now I want to send this data as an attachment in email. Now the problem is I am integrating the data in 3 internal tables into 1 single internal table with the help of  following code :
loop at it1.
    concatenate it1-field1
                       it1-field2
        into itab.
        append itab.
endloop.
loop at it2.
    concatenate it2-field1
                       it2-field2
        into itab.
       append itab.
endloop.
similarly for 3rd internal table. But here it goes wrong.
For each and every field in each record, some specific number of characters are fixed. If any field doesn't uses those characters to complete, it has to leave the remaining characters blank and should start next field from there.
E.g.
Like record is :
AAA reserved chars : 10
XXX " " : 15
YYY " " : 8
so it should print like :
AAA XXX YYY .
But in attachment it is printing like :
AAAXXXYYY.
This is because I am using concatenate function. Please suggest me a way to integrate the data of 3 internal tables into a single internal table including the spaces reserved for each field.
Thanks.

Hi Ravi,
Did u try to use de addicion 'Separated by space'  in the concatenate function?
If it doesn't work, try this...
You have to do as if you want to create a text file, using de offset function.
Creating an internal table with one field and put all the records of your tables into this internal table.
data: wa_line(400).
data: begin of itab_line occurs 0,
           line(400),
        endif itab_line.
Loop at itab1.
clear wa_line.
write: itab1-field1 to wa_line+0(10).
write: itab1-field2 to wa_line+10(8).
write: itab1-fieldN to wa_line+nn(mm).
append wa_line to itab_line.
clear itab_line.
endloop.
Do the same with itab2 and itab3.
