React Collapsing Table

Thanks for taking a look at the react collapsing table. This was inspired by the the jquery datatables library. You can see a working example of this app here. You can also see an example of this app using custom components that has redux hooked up.

This article is a quick dive into some features shown in a very simple example

Features

Expandable Row that makes the table mobile friendly
Prioritization of when columns are shown or hidden as the table expands and shrinks
Search built in with highlighting of content
Creating your own custom react components for each cell
The ability for your custom component to call a function you made outside of the table
The ability to create your own custom pagination component and still call the table functions
The ability to listen for pagination events, like if you need to know if you were on the last page
Ability to overwrite built in icons for sorting and open/closing a row

Installing

To install simply run

npm install react-collapsing-table

This has currently only been tested with react 16.

To use in your project just import it by doing

import ReactCollapsingTable from 'react-collapsing-table'

const yourComponent({ rows, columns }) => {
    <h1>My Cool Collapsing Table!</h1>
    <ReactCollapsingTable rows={ rows } columns={ columns } />
}

Rows and Columns for the above example may look like

rows = [
  { id: 1, firstName: 'Paul', lastName: 'Darragh', }
]
columns = [
  { accessor: 'firstName', label: 'First Name', priorityLevel: 1, position: 1, minWidth: 150, },
  { accessor: 'lastName', label: 'Last Name', priorityLevel: 2, position: 2, minWidth: 150, },
]

Props

Rows (default: [])

This is a list of objects. You can pass more data in than you use and the table will ignore the extra values passed in.

Columns (default: this is required with the following keys also required on each column object)

This is a list of objects that define what data from each row that you want to show the user and where this row should line up.

Each object in this list has the following required attributes that define how and when a column should be hidden or what to display to the user.

accessor: This is used to extra the correct value from a row by setting this to the row's key
- row: { firstName: 'Paul' } The accessor to get the value Paul would be accessor: 'firstName'
label: This is what a user sees at the top of each column
priorityLevel: This tells the table in which order should the columns be popped off in. The higher the number the sooner it will be popped of.
position: This tells the table where to put each column, do you want this to be the first column or the fourth?
minWidth: This tells the table how wide the table can be total and is used to calculate when to pop off columns when the screen width is smaller than the total minWidths of the visible columns

These objects also have several optional attributes that can make the cells displayed under each column do extra work

CustomComponent: This lets you write your own component and pass it to the table
- You must import this component into the file you define where you columns.
CustomFunction: This lets you pass a custom function to help enhance the cell.
- You must pass this to the table as a callbacks object with the key as the accessor and your function as the value.
sortType: This allows you to pass an additional sort type
- currently only the allowed option is 'date' and that sorts assuming the date format is mm/dd/yyyy
sortable: This allows you to disable the sort function for a column.
- true (default): Clicking on the column header will sort by that column
- false: Clicking on the column header will have no effect

showSearch (default: false)

This is a boolean to tell the table whether or not show the search component

showPagination (default: false)

This is a boolean to tell the table whether or not show the pagination component

rowSize (default: 15)

This is a number that tells the table how many rows it should display on a table.

currentPage (default: 1)

This is used to tell the row what page to display if the results are on a different page on the initial load.

column (default: first column in array)

This is used to tell the table if sorting which column should be displayed as sorted (use accessor of the column as the value)

direction (default: 'ascending')

This is used to tell the table which direction the sorted column is displayed in. The 2 valid options are 'ascending' and 'descending'

callbacks

This is an object that is expecting keys that match the accessors of the columns and will allow each column access to a custom function that is mapped to that key.

id

This is a string that you can use to set an id for the table if you need to

paginationEventListener

This is a function that you can pass to the table and when the next or previous button is clicked it will invoke this function and pass a pagination object back that has the the current page, how many pages there are, and the row size

CustomPagination

This is a function that you can pass to the table when you don't want to use the built in pagination component. You will still need to have showPagination set to true.

This function will receive:

currentPage: What page it is on
totalPages: How many pages are there (or the last page)
previousPage: The function to let you go back one page on the table
nextPage: The function to let you go forward a page on the table
goToPage: A function that lets you go to any page.
- Let the user specify the page they want to go to with onChange and it will pick up your value. example <input onChange={ goToPage } />
- Specify the exact page by giving it a newPage value. example goToPage({ newPage: 25 })
inputtedPage: The value to use for goToPage function if you are allowing a user to input a value. example <input value={ inputtedPage } onChange={ goToPage } />

icons

This is an object that allows you to customize the ascending and decending icons on the columns and the open and close row icons on the rows

This object required you use set the following values: openRow, closeRow, ascending, descending. If you want to overRide openRow you must also do the same with closeRow and same for ascending and descending. These values that can be set can take a icon file or regular html. Example:

import ArrowUp from 'react-icons/lib/fa/arrow-up';
import ArrowDown from 'react-icons/lib/fa/arrow-down';

icons: {
        ascending: <svg width="10" height="10"><circle cx="5" cy="5" r="4" stroke="blue" strokeWidth="1" fill="red" /></svg>,
        descending: <svg width="10" height="10"><circle cx="5" cy="5" r="4" stroke="red" strokeWidth="1" fill="blue" /></svg>,
        openRow: ArrowDown,
        closeRow: ArrowUp,
    }

theme

This string is applied as a class name to the container element generated by the ReactCollapsingTable component. You can use this to selectively style different tables, and to remove the default styles applied by this component. See the Styling section for more information.

totalPages

If the data is supplied one page at a time from the server, this property allows setting of the total number of pages in the results-set.

currentPage

If the data is supplied one page at a time from the server, this is the current page.

updateData

If the data is supplied one page at a time from the server, this is the callback function that is fired when the user changes the page. It takes an object as an argument, which should contain the page of data the server should load.

For example, when moving to the next page, the code runs:

this.props.updateData({page: currentPage + 1})

Add your Own Components

This table allows you to create and display your own components. Each column can have their own component and you can pass custom functions or extra information into it.

To pass a custom component you must pass it in a columns prop with the key being CustomComponent and the value being the imported component Example from the travel-receipts initial state

import EmailIcon from '../components/EmailIcon';

columns[
    { accessor: 'email', label: 'Email', priorityLevel: 6, position: 3, minWidth: 150, CustomComponent: EmailIcon },
]

If you decide that you want to pass that custom component the ability to do something you can by passing the table a callBack object with the accessor name as the key and the function you defined as the value Example from the travel-receipts container

import { getEmailIcon } from '../assets/icons/Icon';

clickedImage = ({ imageURL }) => {
    this.props.actions.clickedImage({ imageURL });
}
    
getEmailLogo = ({ email }) => {
    return getEmailIcon({ email });
}

const tableCallbacks = { photo: this.clickedImage, email: this.getEmailLogo }

<ReactCollapsingTable callbacks={ tableCallbacks } />

Styling

We have given most of the components defined class names to make them easy to add your own styles to. A default stylesheet is bundled with the project.

It uses descendant combinators so it only affects elements which are inside a container with class="react-collapsible-theme" which is applied by default to the container generated by the component.

You can override that by passing an alternative theme name, which can be an empty string.

<ReactCollapsingTable theme="" />

We tried to make each this table easy to make your own and have added a number of class names and ids to help make it easy to style and giving them each unique names to avoid name collisions.

Table Data Cell (td)

id: td-${currentRowIndex}-${currentColumnIndex}
- This uses the generated row and column indexes
class name: ${ accessor }
- This uses the column defined attribute as the class name so that you can see all of the attributes that line up to a class name

Table Row (tr)

id: tr-normal-${ rowIndex }
- This uses the genereated row index to define which row it is on
class name: normal-row

Expanded Table Row (tr)

id: tr-expanded-${ rowIndex }
- This uses the genereated row index to define which row it is on
class name: expanded-row

Columns (th)

id: column-${accessor}
- This uses the data accessor as a unique column name

Table (table)

class name: react-collapsible

Search (div)

class name: react-collapsible-search

Clear Search (button)

class name: react-collapsible-clear

Pagination (div)

class name: react-collapsible-page
