This component wants to be a very simple and slim implementation of a exel like table component that will enable you to have:

• resizable columns
• fixed (left) columns
• abililty to customize what is rendered in each cell:
  • using react components
  • passing a formatting function
  • passsing a function that will return which CSS class(es) should be applied to the cell

import Matrix from 'react-matrix'

const data = [
  {
    flightDetails: {
      code: '...',
      date: '...'
    },
    user: {
      details: {
        firstName: '...',
        lastName: '...',
      }
    }
    ...
  }
  ...
]

function classesForAllCells (row) {
  if (row.id === 101010) {
    return 'show-it-red'
  }

  return 'show-it-blue'
}

const columnDefinitions = [
  { label: 'Flight', field: 'flightDetails.code', fixed: true, component: TextCell },
  { label: 'Date', field: 'flightDetails.date', fixed: true, component: DateCell },
  { label: 'First name', field: 'user.details.firstName', component: TextCell },
  { label: 'Last name', field: 'user.details.lastName', component: TextCell },
  { label: 'Something', field: 'someField', formatter: someFormatter },
  { label: 'DOB', field: 'birthday', component: DateCell },
  { label: 'Age', field: 'birthday', component: AgeCell },
]

<Matrix
  data={data}
  columnDefinitions={columnDefinitions}
  classesForAllCells={classesForAllCells}
/>

It is an array of objects (rows) that will be displayed in the matrix

The columnDefinitions is an array of objects, each object can have the following properties:

• label: the string to be show in the table header row
• field: path of the field holding the value to show
• fixed: if true the column will be rendered as a fixed column on the left of the matrix
• formatter: function to which will be passed the value to render, whatever this will return will be rendered instead
• classes: function to which is passed the entire row (object) and should return the cell CSS class(es)
• component: react component to be rendered, it will receive the following props:
  • value: whatever the value for the column is
  • row: the object representing the row that is being rendered
  • field: the same string given in the columnDefinitions for this column

This is a function should return which CSS class(es) should be applied to all cells. It will be called for each object in data passing the current object.

You can add the grid style by importing

import 'react-matrix/css/style.css'

• works only on chrome
• the header cells cannot be resized to less then 100px and more than 500px
• fixed columns are on the left only
• the matrix is rendered all at the same time
