I recently had occasion to use this creating an Upgrade editor for Shadow Warrior 2
for the great table by Zanzer...

I have a function that opens a form in LUA, clears the list view items, and
listens for the user to click on an item:

local lv = FormEditUpgrade.listViewProperties
lv.items.clear()
lv.setOnClick(FormEditUpgrade_listViewProperties_OnClick)

So the form defines the list view with 3 columns. I changed the following properties
when designing the form:

* ColumnClick = False - ??
* ReadOnly = True - don't allow edits directly in the table
* RowSelect = True - select a whole row when clicking
* ViewStyle = vsReport - shows multiple columns with headings

When the last upgrade changes, I analyze the memory and create an array in LUA
of the attributes of that upgrade. I then clear the items array on the list
view and recreate them.

You can see here that ''item.Caption'' controls what is displayed
in the first column. I set the other columns using ''SubItems.text''
by setting it to the values to put in those columns separated by CRLF.
SubItems is a 'Strings' object and there may be a better way to do that,
but this was easy enough for me.

local function LoadUpgrade(address)
CURRENT_UPGRADE = Upgrade(address)
local lv = FormEditUpgrade.listViewProperties
local items = lv.items
items.clear()
for i,attr in ipairs(CURRENT_UPGRADE.attributes) do
local item = items:add()
item.Caption = attr.name
item.SubItems.text = table.concat({ attr.value or 'nil', attr.type }, '\r\n')
end
end

When the user clicks on a row, I use ''ItemIndex'' and match it to
the attribute in my LUA array. The SelectAttribute function handles
using 'inputQuery' to pop up a window for changing the value, changing
the value, and reloading the updated Upgrade.

local function FormEditUpgrade_listViewProperties_OnClick()
if CURRENT_UPGRADE == nil or CURRENT_UPGRADE.attributes == nil or #CURRENT_UPGRADE.attributes == 0 then return end
local lv = FormEditUpgrade.listViewProperties
local selectedIndex = lv.ItemIndex
if selectedIndex < 0 or selectedIndex >= #CURRENT_UPGRADE.attributes then return end
SelectAttribute(CURRENT_UPGRADE.attributes[selectedIndex+1]) -- +1 for 1 based LUA
end
