+#### Table Styles
+
+Define reusable table styles with borders, shading, cell margins, and alignment:
+
+```ruby
+Notare::Document.create("output.docx") do |doc|
+  # Define a custom table style
+  doc.define_table_style :fancy,
+    borders: { style: "double", color: "0066CC", size: 6 },
+    shading: "E6F2FF",

+      doc.td "Widget"
+      doc.td "$10.00"
+    end
+  end
+end
+```
+
+#### Table Style Properties
+
+| Property | Description | Example |
+|----------|-------------|---------|
+| `borders` | Border configuration | `{ style: "single", color: "000000", size: 4 }` |
+| `shading` | Background color (hex) | `"EEEEEE"` |
+| `cell_margins` | Cell padding (twips) | `100` or `{ top: 50, bottom: 50, left: 100, right: 100 }` |
+| `align` | Table alignment | `:left`, `:center`, `:right` |
+
+**Border styles:** `single`, `double`, `dotted`, `dashed`, `triple`, `none`
+
+**Border configuration options:**
+
+```ruby
+# All borders the same
+borders: { style: "single", color: "000000", size: 4 }
+
+# Per-edge borders
+borders: {
+  top: { style: "double", color: "FF0000", size: 8 },
+  bottom: { style: "single", color: "000000", size: 4 },
+  left: { style: "none" },
+  right: { style: "none" },
+  insideH: { style: "dotted", color: "CCCCCC", size: 2 },
+  insideV: { style: "dotted", color: "CCCCCC", size: 2 }
+}
+
+# No borders
+borders: :none
+```
+
+#### Built-in Table Styles
+
+| Style | Description |
+|-------|-------------|
+| `:grid` | Standard black single-line borders |
+| `:borderless` | No borders |
+
+```ruby
+doc.table(style: :borderless) do
+  doc.tr { doc.td "No borders here" }
