React JSON table

Simple React table component to display JSON data.

This is based on excellent react-json-table https://github.com/arqex/react-json-table. The component is written in TypeScript and supports React 19.x. It attempts to be backward compatible with react-json-table.

Features

Features are similar to original react-json-table

• No external dependencies when using pre-built UMD files.
• Customizable cell contents to show your data the way you need.
• Callbacks for clicks on headers, rows or cells.
• Customizable column rendering and ability to add custom columns.
• Customizable CSS class names for table, header, rows and cells.
• No internal state, everything comes from the props.

Additional features

• Props
  • excludeColumns
  • theadClassName
  • caption

- [Column grouping](#column-grouping)

• Support for complex JSON objects

• Support for duplicate id fields in JSON input - correctly renders data-key element.

Table supports complex JSON objects

var rows = [
  {"id": 75950,"name":{"first":"Catherine","last":"Welch"},"age": 24,"phone": "+44 (0)203 437 7302","color": "green"},
  {"id": 80616,"name":{"first":"Goff","last":"Castro"},"age": 36,"phone": "+44 (0)203 279 3708","color": "brown"},
  {"id": 77621,"name":{"first":"Guthrie","last":"Sullivan"},"age": 20,"phone": "+44 (0)203 319 4880","color": "gray"},
];

var columns = [
    {key: 'name.first', label: 'First Name'},
    {key: 'name.last', label: 'Last Name'},
    'age',
    {key: 'phone', label: 'Phone'},
    {key: 'color', label: 'Color'}
];

ReactDOM.render(<JsonTable rows = {rows} columns = {columns}/>, document.body);

Column grouping

Columns can be grouped under same header by specifying group column property.

var rows = [
    {"id":56480,"company":"Plasmox","name":{"first":"Catherine","last":"Welch"},"position":"Regional manager","address":"888 Himrod Street, Independence, Virgin Islands, 3588","phone":"+1 (968) 567-2395","mobile":"+1 (804) 414-3278","email":"[email protected]","registered":"Wednesday, August 27, 2014 11:46 AM"},
    {"id":27368,"company":"Accidency","name":{"first":"Goff","last":"Castro"},"position":"Operations manager","address":"295 Bogart Street, Defiance, Marshall Islands, 8354","phone":"+1 (831) 510-2392","mobile":"+1 (840) 446-2807","email":"[email protected]","registered":"Monday, November 9, 2015 7:37 PM"},
    {"id":44914,"company":"Viagreat","name":{"first":"Guthrie","last":"Sullivan"},"position":"Office manager","address":"802 Wythe Place, Jardine, Ohio, 7435","phone":"+1 (990) 409-3109","mobile":"+1 (875) 417-3069","email":"[email protected]","registered":"Tuesday, December 6, 2016 11:38 AM"},
    ];

var columns = [
    {key: 'company', label: 'Company'},
    {key: 'name.first', label: 'First Name', group: 'Employee'},
    {key: 'name.last', label: 'Last Name', group: 'Employee'},
    {key: 'position', label: 'Position', group: 'Employee'},
    {key: 'address', label: 'Address', group: 'Contact Details'},
    {key: 'phone', label: 'Phone', group: 'Contact Details'},
    {key: 'mobile', label: 'Mobile', group: 'Contact Details'},
    {key: 'email', label: 'Email', group: 'Contact Details'},
    {key: 'registered', label: 'Registered'}
];

ReactDOM.render(<JsonTable rows = {rows} columns = {columns}/>, document.body);

Exclude columns

This allows to exclude columns from table without defining all columns.

var rows = [
    {"id": 75950,"name":{"first":"Catherine","last":"Welch"},"age": 24,"phone": "+44 (0)203 437 7302","color": "green"},
    {"id": 80616,"name":{"first":"Goff","last":"Castro"},"age": 36,"phone": "+44 (0)203 279 3708","color": "brown"},
    {"id": 77621,"name":{"first":"Guthrie","last":"Sullivan"},"age": 20,"phone": "+44 (0)203 319 4880","color": "gray"},
];

var excludeColumns = [
    'id'
];
 
ReactDOM.render(<JsonTable rows = {rows} excludeColumns = {excludeColumns}/>, document.body);

If both columns and excludeColumns props are passed, columns will be excluded even if they are defined in columns prop.
