Table.tsx

/**
 * Feature:
 *  - fixed not need to set width
 *  - support `rowExpandable` to config row expand logic
 *  - add `summary` to support `() => ReactNode`
 *
 * Update:
 *  - `dataIndex` is `array[]` now
 *  - `expandable` wrap all the expand related props
 *
 * Removed:
 *  - expandIconAsCell
 *  - useFixedHeader
 *  - rowRef
 *  - columns[number].onCellClick
 *  - onRowClick
 *  - onRowDoubleClick
 *  - onRowMouseEnter
 *  - onRowMouseLeave
 *  - getBodyWrapper
 *  - bodyStyle
 *
 * Deprecated:
 *  - All expanded props, move into expandable
