You can set weights to columns, default weight for all columns is 0, columns
are ordered in ascending order, so -10 weight goes before 0 weights. When you
access to config.action.columns (to add or exclude columns for example),
columns are copied from config.columns, so set your weights before adding or
excluding columns from specific actions.
For example, a model has columns name, surname, birthday, email and phone.
Default columns order is birthday, email, name, phone, surname. To set name
and surname as first fields, and add a virtual column to list action, you can
use:
config.columns << :age #create a virtual column
config.columns.exclude :age # exclude from all actions
config.columns[:name].weight = -100
config.columns[:surname].weight = -50
config.list.columns << :age # add to list columns
If you want age column next to birthday, and you don't want to set a fixed
array for config.list.columns, you can exclude age for each action.
config.columns << :age #create a virtual column
config.columns[:name].weight = -100
config.columns[:surname].weight = -50
config.columns[:birthday].weight = -25
config.columns[:age].weight = -20
config.actions.each {|action| config.send(action).columns.exclude :age unless
action == :list }
