[Table] Column with id '${columnId}' does not exist.

Error message

[Table] Column with id '${columnId}' does not exist.

What it means

table.getColumn(columnId) looks up the id in the flat column-by-id map and warns in development when no column with that id exists. The library returns undefined rather than throwing, but the warning signals that downstream code operating on the column will misbehave.

 * The lookup can return group columns or leaf columns. In development, a
 * missing id logs a warning to help catch stale column references.
 *
 * @example
 * ```ts
 * const column = table_getColumn(table, 'firstName')

Solutions

1. Log table.getAllFlatColumns().map(c => c.id) and use an id that exists.
2. Correct the columnId string/typo to match a declared column id.
3. If the column may be absent, guard the result: const col = table.getColumn(id); if (!col) return.
4. Ensure the call happens after table state/columns are initialized (not during initial render before columns resolve).

Example fix

// before
table.getColumn('userNme')?.toggleVisibility()

// after
const col = table.getColumn('userName')
if (col) col.toggleVisibility()

const knownIds = new Set(table.getAllFlatColumns().map(c => c.id))
if (!knownIds.has('userName')) {
  throw new Error('userName column not declared')
}

function columnExists(table: Table<any, any>, id: string): boolean {
  return table.getAllFlatColumnsById()[id] !== undefined
}

const col = table.getColumn(id)
if (col === undefined) {
  console.warn(`Skipping operation: column '${id}' not found`)
  return
}
col.toggleVisibility()

When it happens

Trigger: Calling table.getColumn('someId') where 'someId' is not a declared column id: typos, referencing a column removed or renamed, calling before column state is initialized, or passing a columnDef header/accessor string that differs from the resolved column id.

Common situations: Renaming a column id without updating visibility/pinning/sorting calls; using the header text instead of the id; dynamic columns from config that were filtered out; grouping code referencing a nonexistent column.
