+#### 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 |
+
 ### Images
 
 Images can be added to paragraphs, table cells, and list items. Supports PNG and JPEG formats.
