reactabular-easy - Easy, opinionated wrapper for Reactabular

Given Reactabular is flexible by design, it's not the easiest to use and you may have to do quite a bit of wiring to make it work the way you want. reactabular-easy has been designed to make using it easier. It is opinionated and takes away some power. But on the plus side it allows you to render a fully featured table faster.

How to Use?

To make the drag and drop functionality work, you have to set up react-dnd-html5-backend or some other React DnD backend.

You can find suggested default styling for the package at style.css in the package root.

If you want to use the drag and drop functionality, you have to set up React DnD!

Styling

It is possible to pass custom classNames and props as listed below:

classNames: {
  table: null,
  header: {
    wrapper: null
    // TODO
    /*
    row: null,
    cell: null
    */
  },
  body: {
    wrapper: null
    // TODO
    /*
    row: null,
    cell: null
    */
  }
},
props: {
  resize: {
    container: {
      style: {
        color: 'red'
      }
    },
    value: {},
    handle: {}
  },
  sort: {
    container: {},
    value: {},
    order: {}
  }
}

For more control, you can also override components and also inject styling and class names through the column definition and the onRow handler.

Customization

If you want to customize resize/sort controls further (add classNames etc.), pass props like this:

props: {
  resize: {
    container: {},
    value: {},
    handle: {}
  },
  sort: {
    container: {},
    value: {},
    order: {}
  }
},
