Excel Function - How to excluding certain alphabetically -


i using following function build series of running number in excel file.

"=left(address(row(aa1),column(aa1)+(row(a1:a1)-1),4),2)"

the lists shown in file similar like: aa,ab,ac,ad,...

enter image description here

now, trying exclude alphabetical (such "g, i, o") list, not know how start it.

any advise?

remarks: exclude (g, i, o) -> "ag,ai..,ga,gb...oz"

thanks.

set cell a1 "aa".

in cell a2 put following formula:

=if(find(right(a1,1),"abcdefghijklmnopqrstuvwxyz")=len("abcdefghijklmnopqrstuvwxyz"),mid("abcdefghijklmnopqrstuvwxyz",find(left(a1,1),"abcdefghijklmnopqrstuvwxyz")+1,1)&"a",left(a1,1)&mid("abcdefghijklmnopqrstuvwxyz",find(right(a1,1),"abcdefghijklmnopqrstuvwxyz")+1,1))

you can drag down how many ever rows need. might complicated, simple if break down.

to exclude chars "g", "i" , "o", remove them everywhere see "abcdefghijklmnopqrstuvwxyz". become "abcdefhjklmnpqrstuvwxyz". might better put list of chars cell , reference cell instead of repeating string many times in formula.

scala - 'wrong top statement declaration' when using slick in IntelliJ -

Image
i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
