+#### 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",
+    cell_margins: 100,
+    align: :center
+
+  # Apply the style to a table
+  doc.table(style: :fancy) do
+    doc.tr do
+      doc.td "Product"
+      doc.td "Price"
+    end
+    doc.tr do
+      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" }
+end
+```
+
+#### Column Sizing
+
+Control table column widths with layout modes and explicit sizing.
+
+**Auto-layout** - columns adjust to fit content:
+
+```ruby
+doc.table(layout: :auto) do
+  doc.tr do
+    doc.td "Short"
+    doc.td "This column expands to fit longer content"
+  end
+end
+```
+
+**Fixed column widths** - specify widths for all columns:
+
+```ruby
+# Inches
+doc.table(columns: %w[2in 3in 1.5in]) do
+  doc.tr do
+    doc.td "2 inches"
+    doc.td "3 inches"
+    doc.td "1.5 inches"
+  end
+end
+
+# Centimeters
+doc.table(columns: %w[5cm 10cm]) do
+  doc.tr { doc.td "5cm"; doc.td "10cm" }
+end
+
+# Percentages
+doc.table(columns: %w[25% 50% 25%]) do
+  doc.tr { doc.td "Quarter"; doc.td "Half"; doc.td "Quarter" }
+end
+```
+
+**Per-cell widths** - set width on individual cells:
+
+```ruby
+doc.table do
+  doc.tr do
+    doc.td("Narrow", width: "1in")
+    doc.td("Wide", width: "4in")
+  end
+end
+```
+
+**Combined layout and columns:**
+
+```ruby
+doc.table(layout: :fixed, columns: %w[2in 2in 2in]) do
+  doc.tr do
+    doc.td "A"
+    doc.td "B"
+    doc.td "C"
+  end
+end
+```
+
+**Width formats:**
+
+| Format | Example | Description |
+|--------|---------|-------------|
+| Inches | `"2in"` | Fixed width in inches |
+| Centimeters | `"5cm"` | Fixed width in centimeters |
+| Percentage | `"50%"` | Percentage of table width |
+
