Column settings for exports

Updated November 15, 2026rowpine 1.0.3

A table with formatted dates, amounts, colored margins and status badges.

Per-column export settings go in the column's meta.rowpine. Your table renders as before; Rowpine reads these only when it writes a file.

helper.accessor("amount", {
  header: "Amount",
  cell: (c) => money.format(c.getValue()),
  meta: {
    rowpine: {
      numFmt: '"$"#,##0.00',
      format: (v) => money.format(v as number),
      cellStyle: (v) => ((v as number) < 0 ? { color: "#b91c1c" } : undefined),
    },
  },
})

Key	Used by	What it does
`header`	all	Header text in the file. Default: the column's string `header`, else its id.
`numFmt`	Excel	Excel number format. See number and date formats.
`format`	PDF	Text for a value. Default: numbers and dates in the browser's locale.
`cellStyle`	Excel, PDF	`{ fill, color, bold }` for a cell. See cell colors.
`width`	Excel	Width in pixels. Default: the column's TanStack size.
`align`	Excel, PDF	`left`, `center` or `right`. Default: right for numbers.
`exclude`	all	Never export this column. Display columns (no accessor) are excluded unless this is `false`.

With TanStack v9, type meta by adding a column meta slot to your features:

import type { RowpineColumnMeta } from "rowpine"

const features = tableFeatures({
  // ...your features
  columnMeta: metaHelper<{ rowpine?: RowpineColumnMeta<Order> }>(),
})

With v8, add rowpine?: RowpineColumnMeta<TData> to the ColumnMeta interface through module augmentation.
