small table with index

[Jay Ess 6]

I want to build an array with data as in local tb ={1=a,2=b,3=c} and so on.

 

one question,

1 - I notice that i cant add a number as the index as above? unless i am doing something wrong?

k,k  => k,v ?

Thank you @jgab yes that worked, it messing with the sort but as i am only using it for a lookup and return value am I correct that I dont have to worry about that? all keys and values are unique.

What error do you get?

not sure if this was also posted

 

re the error i have 5 sheets in the qa in one of the sheets i get this error

attempt to call a nil value (global 'create2wayTable')

 

however on another sheet it does work!

[Jay Ess 6]

i have made a function as:

 

function createTempTable(year)

i then populate the table based on the year variable which i pass in.

as local pTb = create2wayTable()

local pIx = 1

pTb.add(pIx,"one")

pIx = pIx +1

pTb.add(pIx,"two")

and so on, the reason why i am using pIx is because depending on the variable passed in the funtion it will then build a different table for the year.

 

the table is being built properly and i can debug it from with in the function by,

for k,v in pairs(pTb.tab) do print(k,v) end.

 

so my question is how do i refernece this table in order to make use of the key and value in it please?

from another function i want to call this table and then be able to get either the index or the value, but am a bit stuck on how do that?

 

can you guide me please?

 

after a bit of firther messing i have done this:

in the create2way function

return pTb

 

and then in the first function:

pYear = createTempTable(year) 

 

local getB= pYear.lookupKey("Bee")

 

which returns me 2

 

i assume this is the correct way of doing it?
