new line

[PassivPluss]

Hi in this for function, the texts are stringed together and sent on an email. This is for the alarm window 
But what do I have to add in the end to get a new line between each alarm entry?

I tried to send mail in the for function directly but only the last alarm is then sent by email for some reason. Why is that?

what do i use to get the number for the current row in the rows function?

What do I use to get the total number of rows in the table?

maileksport = " "
for _, row in ipairs(rows) do
  alstmaxid = math.max(alstmaxid, row.id)
  alertdate = os.date('%c', row.alerttime)
  maileksport = maileksport .. (  "Alarmnr \n \n " .. " - " .. ((alertdate .. " - ".. row.alert  )) ) --- here i want a new line
    --  mail(mailalarm, (lokasjon ..  " - ALARM " ), alertdate .. " - ".. row.alert )   --- this only send the last entry in table as alarm

   
end
