It's not a solution but a hint.. maybe. If you have time for that, you could try using ActiveXServer or .NET. Here is an example for building a table with .NET (that I saved once from a thread on StackOverflow):
%# Register Word assembly
NET.addAssembly('microsoft.office.interop.word');
%# Create an instance of Word
wordApp = Microsoft.Office.Interop.Word.ApplicationClass;
%# Get the object that handles documents
wordDoc = wordApp.Documents;
%# Add a new document
newDoc = wordDoc.Add;
%# Make Word visible
wordApp.Visible = true;
%# Get the selection object to manage selected area
selection = wordApp.Selection;
%# Create a table
table = newDoc.Tables.Add(selection.Range, 3, 5);
%# Add grid lines
table.Style = 'Table Grid';
About ActiveXServer, just Google
actxserver('Word.Application')
I didn't investigate further because I had no use for it, but if I had to insert an image in a Word document, this is probably where I would start.
