I'm using the example of your website: https://bryntum.com/examples/grid/celledit/.
I changed the column snippet as follows:
{ text : 'Name', field : 'name', flex : 1, editor : { readonly : true } },
{ text : 'check', field : 'done', type : 'check', editor : { readonly : true, type : 'boolean'} },
I'm trying not to allow the columns to be modified, but this isn't working.
What am I doing wrong?
