Try this:
list=table.pack(1,2,3,nil,4,5,nil,nil,6,7)
local n=0
for i=1,list.n do
if list[i]~=ni then
n=n+1
list[n]=list[i]
end
end
list.n=n
for k,v in ipairs(list) do print(k,v) end
This is a little like one of my solutions, but neater. Thanks.
However, #list is still 10. One needs, before resetting list.n,
for i=n+1,list.n do list[i]=nil end
Would this work?
list=table.pack(1,2,3,nil,4,5,nil,nil,6,7)
local n=0
for i=1,list.n do
if list[i]~=nil then
n=n+1
list[n]=list[i]
list[i]=nil
end
end
list.n=n
for k,v in ipairs(list) do print(k,v) end
