Thread:Project:Support desk/Please help to align a table

Hello all,

I started to use Wikimedia this week and i have a problem with cell,

I wrote this : {|border="1" {|
 * Planification

But I obtained a bad result : the colomns are not aligned, I need to have all colomns aligned, but I don't know how to do this with a table like this :

Do you know how to align all columns ??
