The RowDetailPlugin displays detailed information about a selected row in a side panel. It’s commonly used with the row-click event to show row details when users click on table rows.

​
Installation

npm install @izumisy/seizen-table-plugins

​
Import

import { RowDetailPlugin } from "@izumisy/seizen-table-plugins/row-detail";

​
Basic Usage

import { useSeizenTable, SeizenTable, useSeizenTableEvent } from "@izumisy/seizen-table";
import { RowDetailPlugin } from "@izumisy/seizen-table-plugins/row-detail";

function UsersTable() {
  const table = useSeizenTable({
    data,
    columns,
    plugins: [RowDetailPlugin.configure({ width: 350 })],
  });

  // Open side panel when row is clicked
  useSeizenTableEvent(table, "row-click", (row) => {
    table.plugin.open("row-detail", { row });
  });

  return <SeizenTable table={table} />;
}

​
Features

The RowDetailPlugin automatically:
  • Displays all fields - Shows all properties of the selected row object
  • Formats values - Formats object and array values as pretty-printed JSON
  • Updates dynamically - Updates content when clicking different rows while panel is open
  • Handles nested data - Properly displays nested objects and arrays

​
Opening the Panel

There are two ways to open the row detail panel:

​
Using the row-click Event

The most common pattern is to open the panel when a row is clicked: 
import { useSeizenTableEvent } from "@izumisy/seizen-table";

function MyTable() {
  const table = useSeizenTable({
    data,
    columns,
    plugins: [RowDetailPlugin.configure({ width: 350 })],
  });

  useSeizenTableEvent(table, "row-click", (row) => {
    table.plugin.open("row-detail", { row });
  });

  return <SeizenTable table={table} />;
}

​
Programmatic Control

You can also open the panel programmatically for a specific row: 
function MyTable() {
  const table = useSeizenTable({
    data,
    columns,
    plugins: [RowDetailPlugin.configure({ width: 350 })],
  });

  const showUserDetails = (user: User) => {
    table.plugin.open("row-detail", { row: user });
  };

  return (
    <div>
      <button onClick={() => showUserDetails(data[0])}>
        Show First User
      </button>
      <SeizenTable table={table} />
    </div>
  );
}

​
Dynamic Updates

When the row detail panel is already open, clicking on a different row will update the panel content: 
useSeizenTableEvent(table, "row-click", (row) => {
  // Panel automatically updates if already open
  table.plugin.open("row-detail", { row });
});

​
Value Formatting

The plugin automatically formats different value types:
  • Primitives - Displayed as-is (strings, numbers, booleans)
  • null/undefined - Displayed as empty
  • Objects - Pretty-printed as JSON
  • Arrays - Pretty-printed as JSON
  • Dates - Converted to string representation
type User = {
  id: number;
  name: string;
  email: string;
  metadata: {
    lastLogin: string;
    preferences: string[];
  };
  tags: string[];
};

const user = {
  id: 1,
  name: "John Doe",
  email: "john@example.com",
  metadata: {
    lastLogin: "2024-01-15",
    preferences: ["email", "sms"],
  },
  tags: ["premium", "verified"],
};

// When opened, the panel will display:
// id: 1
// name: John Doe
// email: john@example.com
// metadata: { "lastLogin": "2024-01-15", "preferences": ["email", "sms"] }
// tags: ["premium", "verified"]

Complete Example

import { useSeizenTable, SeizenTable, useSeizenTableEvent } from "@izumisy/seizen-table";
import { RowDetailPlugin } from "@izumisy/seizen-table-plugins/row-detail";
import type { ColumnDef } from "@izumisy/seizen-table";

type Customer = {
  id: number;
  name: string;
  email: string;
  company: string;
  status: string;
  metadata: {
    signupDate: string;
    totalOrders: number;
    lastOrderDate: string;
  };
  tags: string[];
};

const columns: ColumnDef<Customer>[] = [
  { accessorKey: "id", header: "ID" },
  { accessorKey: "name", header: "Name" },
  { accessorKey: "email", header: "Email" },
  { accessorKey: "company", header: "Company" },
  { accessorKey: "status", header: "Status" },
];

function CustomersTable({ customers }: { customers: Customer[] }) {
  const table = useSeizenTable({
    data: customers,
    columns,
    plugins: [
      RowDetailPlugin.configure({ width: 400 }),
    ],
  });

  // Open detail panel when a row is clicked
  useSeizenTableEvent(table, "row-click", (customer) => {
    console.log("Viewing customer:", customer.id);
    table.plugin.open("row-detail", { row: customer });
  });

  return <SeizenTable table={table} />;
}

​
Use Cases

Display full user profiles including metadata, permissions, and activity logs when clicking on a user row.
Show complete order information including line items, shipping details, and payment information.
View full log entries with stack traces, metadata, and timestamps when investigating issues.
Display comprehensive product details including specifications, pricing history, and inventory across warehouses.

​
Tips

The row detail panel is ideal for displaying fields that don’t fit in the table columns, such as long text, nested objects, or metadata.
You can close the panel programmatically using table.plugin.close("row-detail").
Make sure to pass the full row object to table.plugin.open(), not just the row ID. The plugin needs access to all row fields.
