Description

A spreadsheet table is a type of data table where users can add and edit numeric data on a grid

Usage & Behaviour

Structure

• The table contains a grid of rows and columns

• The table may contain:

  • Header row

  • Header column (on the left)

  • Total row (at the bottom)

• If the table is higher than its container, a scroll bar will appear. The scroll bar will not affect the header and title rows, if exists

States

• A cell can be in one of these states:

State	Example	Comments
Normal (Enabled)
Mouseover
Selected
Selected + In Focus		Only one cell can be in focus at any time. By default, the top-left cell is in focus
Disabled
No Data
Error		See Field Validation

Interaction

• Clicking a cell:

  • Sets the focus to the cell

  • Selects the cell

  • Deselects all other cells

  • If the cell contains text - selects the text, allowing the user to edit it

• Double clicking a cell is similar to clicking a cell, but if the cell has text in it, it will place the insertion point in the cursor’s location. Currently they are same

• Hitting the Enter / Tab key:

  • Saves the text in the cell (if exists)

  • Sets the focus to the cell below / to the right of the current cell respectably, while skipping disabled cells. Currently Enter deselects the cell but keeps the focus

  • If the new cell contains text - selects the text

  • If the new cell does not contain text - showing the insertion point, allowing the user to enter text

• Selecting multiple cells can be done in one of two ways:

  • Dragging the cursor over a group of cell. In this case the first selected cell gets the focus - currently ExtJS only marks the cell

  • Clicking cells while holding the Ctrl / Cmd key. In this case the last selected cell gets the focus - currently does not work in ExtJS

  • Shift to select group of cells - currently does not work in ExtJS

• A cell in focus or a group of cells that were selected by dragging will show a special handle at the bottom-right corner of the cell / the selected area (see image) - in ExtJS works only on a single cell

  • Mouseover the handle will switch the cursor to a cross

  • Dragging the handle will copy the content of the cell to the target cells

• The user can cut, copy and paste cell content using Ctrl / Cmd + X, C and V respectably

Edge Cases

• Edge cases may include:

  • Typing long text in a cell

  • Typing invalid data in a cell

  • Deleting mandatory cells

  • Server error when trying to save cell content

• For more information please refer to the Field Validation page

Best Practices

• Use a spreadsheet table When it supports another set of data, for example, a graph

Accessibility compliance

<<In general each component should be A11y complied,  please follow the 3 guidelines linked below. At the very least we should document that each component is in compliance with each of the 3>>

Focus management

<<How will the component work with keyboard only - without a mouse. Can be reference if written above

We already set a general guidelines described in /wiki/spaces/UX/pages/308969693 >>

Screen reader support 

 <<Make sure the components support screen reader for content or behaviour where needed - see /wiki/spaces/UX/pages/308248620 >>

Contrast & size compliance

<<Visual designers must comply with the minimal of /wiki/spaces/UX/pages/301498483 for each component>>
