`useTableContext` must be used within an `AppTable` componen

Error message

`useTableContext` must be used within an `AppTable` component. Make sure your component is wrapped with `<table.AppTable>...</table.AppTable>`.

What it means

`useTableContext` in the Solid adapter reads the Solid context provided by `<table.AppTable>`. When no provider exists above the calling component, the context is undefined and this error is thrown. It prevents table APIs from being used without a table instance.

Solutions

Wrap the consuming component with `<table.AppTable table={table}>...</table.AppTable>`.
Move the component into AppTable's children within the same reactive root.
Dedupe solid-table versions so the context module is shared.
Read the context directly (`useContext(TableContext)`) and handle undefined if usage is optional.

Example fix

// before
function RowCount() {
  const table = useTableContext()
  return <span>{table.getRowModel().rows.length}</span>
}

// after
<table.AppTable table={table}>
  <RowCount />
</table.AppTable>

Defensive patterns

Strategy: validation

Validate before calling

import { useContext } from 'solid-js'
import { TableContext } from '@your-scope/solid-table'

function useSafeTable() {
  const table = useContext(TableContext)
  if (!table) {
    console.error('useTableContext requires <table.AppTable> above this component')
  }
  return table
}

Type guard

function hasTable<T>(t: T | null | undefined): t is T {
  return t != null
}

Try / catch

try {
  const table = useTableContext()
  // use table
} catch (err) {
  if (err instanceof Error && err.message.includes('useTableContext')) {
    return null // not inside <table.AppTable>
  }
  throw err
}

Prevention

Render Solid table consumers only inside <table.AppTable> children.
Avoid solid Portal usage that escapes the provider subtree.
Dedupe solid-table versions in the lockfile.
Use a test helper that wraps subjects in AppTable.

When it happens

Trigger: Calling `useTableContext()` outside `<table.AppTable table={table}>`'s subtree; rendering consumers via Portal (solid-js/web) outside the provider; duplicated solid-table installs with separate context identities.

Common situations: Custom Solid toolbar/control components placed outside AppTable; test harnesses mounting only the child; refactors that extracted components from AppTable children.
