Nattable saveState and loadState issue [message #1818629]

i ran into problems when storing settings for nattable

Description of my problem:

as far as i understand NatTable stores configs with index of the column as key.
this does not work for me as its possible that those indexes change with updates for my application (added fields - see below)

this is nattable specific and ok -> i need to write my own saveState.

how does nattable store the width of a column (its not in the properties file - is it?) i was not able to find this in the saveState - properties (did i miss it? and its there?)

further

when i change the config of the table (add columns -> indizes change) so the config is corrupted - wrong columns pop up, reordering is corrupt or nothing gets shown up at all (as mentioned above - this is no blame on nattable - as i do change the column count!)

finally to come to my question:

how can i get and get the width for columns?

EDIT: is it this: BODY.NONFROZEN_REGION.columnWidth.sizes=902\:38,928\:335,
column#902=38, only non defaults are saved?

how can i get and set the width for columns?
is there a command for setting multiple/all widths?

EDIT: so the simplest way would be patching the "properties"

The column widths are stored in the SizeConfig inside the DataLayer. There is API in the DataLayer to modify the dimensions. And there are also resize commands, e.g. the MultiColumnResizeCommand (hope the name is correct).

Yes I think the defaults are not saved for every column. Only if it is resized it needs to be stored. For the details in names etc. you should check the sources of SizeConfig and DataLayer. And yes, if you modify the underlying data structure so the stored state does not match anymore, you need to patch the properties.
