disable a column in an editable interface

Use showWhen parameter in Grid header cell and in gridRowLayout's contents, then add condition a!isUserMemberOfGroup( UserName, {Groups})

Example:

a!localVariables(
local!items: {
{ item: "Item 1", qty: 1, unitPrice: 10 },
{ item: "Item 2", qty: 2, unitPrice: 20 }
},
a!gridLayout(
label: "Products",
instructions: "Update the item name, quantity, or unit price.",
headerCells: {
a!gridLayoutHeaderCell(label: "Item", showWhen:a!isUserMemberOfGroup( UserName, {Groups})),
a!gridLayoutHeaderCell(label: "Qty"),
a!gridLayoutHeaderCell(label: "Unit Price"),
a!gridLayoutHeaderCell(label: "Total", align: "RIGHT")
},
rows: {
a!gridRowLayout(
contents: {
a!textField(
value: local!items[1].item,
saveInto: local!items[1].item,
showWhen: a!isUserMemberOfGroup( UserName, {Groups})
),
a!integerField(
value: local!items[1].qty,
saveInto: local!items[1].qty
),
a!floatingPointField(
value: local!items[1].unitPrice,
saveInto: local!items[1].unitPrice
),
a!textField(
value: a!currency(
isoCode: "USD",
value: tointeger(local!items[1].qty) * todecimal(local!items[1].unitPrice)
),
readOnly: true,
align: "RIGHT"
)
}
),

},
rowHeader: 1
)
)
