@mrblunderovich/react-json-table-modified v0.1.0

This is a modified 'react-json-table' package

This package has been created as part of an exercise. Do not use it for important stuff. Seems to work with React18. Code has been updated by ChatGPT. Beware.

A simple but flexible table react component to display JSON data.

As simple as feeding it with an array of objects.

var items = [
  { name: "Louise", age: 27, color: "red" },
  { name: "Margaret", age: 15, color: "blue" },
  { name: "Lisa", age: 34, color: "yellow" },
];

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

Usage

You can see the simplest example of use at the top of this page, but probably you would like to customize a bit the behaviour of the table to adapt it to your needs. Have a look at the accepted component props.

props

Column definition

Using column definitions you can change the behaviour of the column easily. To do so you need to pass an array of the column definitions as the columns prop to the JsonTable:

var items = [
  { name: "Louise", age: 27, color: "red" },
  { name: "Margaret", age: 15, color: "blue" },
  { name: "Lisa", age: 34, color: "yellow" },
];

var columns = [
  "name",
  { key: "age", label: "Age" },
  {
    key: "color",
    label: "Colourful",
    cell: function (item, columnKey) {
      return <span style={{ color: item.color }}>{item.color}</span>;
    },
  },
];

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

As you can see in the example, a column definition can be just a string with the name of the field to display or an object. But if an object is passed the customization can be much more. A column definition can be an object with the following properties:

• key: It is the internal name use for the column by JsonTable. It is added to the className of the cells and headers to apply styles to the column. It is also passed as an argument for the click callbacks. If the column definition has no cell property, it also represent the property of the current row to be shown as cell content.
• label: It is the content of the column header. You can use a string or a ReactComponent to show inside the header cell.
• cell: What is going to be displayed inside the column cells. It can be a string or ReactComponent to show static contents, but tipically it is a function( rowData, columnKey ) that return the contents for the cell. This way different contents are shown in the column for different rows.

Table settings

Using the prop settings we can customize some details that are not related to columns. It is an object with the following properties:
