Using components in a table don't work with a container.

I've a table in which I want to show some boolean as checkbox or some other value as component (buttons, icons etc...)
In a first version I defined the property type as checkbox, I added a checkbox to my item and then added the item to the table : it worked.
Now I was forced to create a container in order to manage the pagination and then I defined the property type as checkbox, I added a checkbox to my item and then I return the item whithin a collection but now I see the toString of my checkbox (and of each object I put).
Also alignments are lost (they worked "before the container").
What's wrong ?
What did I forget ?

I would suggest that instead of keeping components in your container, you should just keep the data there and use a ColumnGenerator for creating components that represent your data.

What about alignemt ?
should I use the ColumnGenerator ?
How?

Sorry but I don't understand Your suggestion about ColumnGenerator.
In my table I've no addContainerProperty in my code and fields are "automatically generated from getIds() provided from the container (I think).
So how can I force the column to be generated from a ColumnGenerator ?

you can add extra properties or override old ones with table.addGeneratedColumn(propertyId, ColumnGenerator)
