Side-by-side rows

Row lays content side by side - the tool for letterheads, address blocks, and any two-column arrangement that isn’t tabular data.

Relative and fixed items

doc.Row(row => row
    .RelativeItem(left => left
        .Text("Billed to", Label)
        .Text("Acme Corp.", Section),
        weight: 1.2f)
    .FixedItem(210f, right => right
        .Text("Invoice date", Label)
        .Text("09 Jul 2026", Body)));

• RelativeItem(configure, weight) - shares the width left over after fixed items, proportionally to weight (default 1f).
• FixedItem(width, configure) - exactly width points.

Each item is itself a container: it accepts the same Text calls a paragraph does, stacked vertically.

Rows vs. tables

Use a row when you’re arranging blocks of content spatially. Use a table when the data is tabular - tables add borders, cell backgrounds, spans, and repeating headers. A borderless table can emulate a row, but rows express the intent more directly and compose more naturally with paragraphs around them.

Example: the invoice letterhead

doc.Row(row => row
    .RelativeItem(left => left
        .Text("INVOICE", Title)
        .Text("INV-20260709-001", new TextStyle(Color: Colors.Blue.Medium)),
        weight: 1.35f)
    .RelativeItem(right => right
        .Text("Northwind Studio Ltd", Section)
        .Text("12 Harbour Lane", Body)
        .Text("London EC1V 4AB", Body)));

This is the top of your first invoice - the title block takes a bit more than half the width, the sender block the rest.
