Hidden and excluded columns

The file has the columns the user can see, in the order they see them.

• A column hidden with TanStack's column visibility is left out. In the image, Country is hidden, so the file has no Country column.
• Columns pinned to the start come first, then the rest, then columns pinned to the end, as on screen.
• Display columns, the ones without an accessor such as selection checkboxes and row actions, are left out: they have no value to write.
• A column with exclude: true never goes to a file, even when it is visible. Use it for internal ids and other data columns that should stay on screen only:

helper.accessor("id", { header: "Internal id", meta: { rowpine: { exclude: true } } })

exclude: false keeps a display column in the file.

If a column's header is a function (an icon, a sort button), set the file's header text with meta.rowpine.header; otherwise the column id is used.
