Pass sizeTable lambda params instead of discard param

.SetCommand(table, async **sizeTable** =>
{
...
   var dialog = new FamilySizeTableDialog(context.ServiceProvider, **sizeTable**);

Because you pass table as parameter to the command

Instead of UnitUtils.IsUnit(typeId) you need to use typeId.Empty() check and remove REVIT2022_OR_GREATER directive

We can add unit in column header ? like .csv file?

    private void CreateColumns(FamilySizeTable table)
    {
        for (var i = 0; i < table.NumberOfColumns; i++)
        {
            var typeId = table.GetColumnHeader(i).GetUnitTypeId();
            var headerName = table.GetColumnHeader(i).Name;
            
            var columnName = typeId.Empty() ? headerName : $"{headerName}##{typeId.ToUnitLabel()}";
            Columns.Add(new DataColumn(columnName, typeof(string)));
        }
    }

AutoGenerateColumns true by default, can remove it

[Nice3point]

IsReadOnly="True"
HeadersVisibility="Column"
CanUserReorderColumns="False"

We can add those properties for better readability and remove scrollViewer because DataGrid has scroll by default in the template

[Nice3point]

we can remove it, the content takes up all available space

[Nice3point]

I guess it's better to remove the max width if we want to see large horizontal tables in the full screen mode

@SergeyNefyodov I've cleaned the code a bit on the comments above, it looks like:

Compare with before:

Maybe the drawback is the Column1 name for the first column, but DataTable doesn't support empty name
