OI Lume Viz
0.16.5

Table Since 0.8.0

Merge rows, use colour scales and sort columns.

When making tables it is useful to keep in mind the advice on table elements from the Royal Statistical Society.

Usage

To use this component in a Nunjucks template you would add the following (assumes you've loaded OI Lume Viz into componentNamespace: 'oi'):

{% comp 'oi.table', { "config": config } %}{% endcomp %}

where config is replaced by an object that contains some or all of these variables:

  • data - (required) Either a reference to a CSV file in the Lume site or an array of rows with named attributes
  • columns - An ordered array of columns to use to build the table. You could also create a virtual column here. Each is of the form:
    • name - (required) The title of the column in the data.
    • align - Set the text alignment of the column e.g. left, center, or right
    • mergerows - (boolean) if this column contains neighbouring rows with the same value, these will be merged into one cell.
    • sortable - (boolean) if this column will be made sortable by the viewer. Note that it isn't possible to make a column sortable if mergerows has been used on any column.
    • colour - A hex colour to use for the background colour of the cells in this column.
    • template - A virtual column can be created from other columns in the data.
    • scale - A colour scale to use to set a cell's background colour based on the cell value.
    • min - Used with scale and max to define the colour scale. If not included, the minimum value of the column will be used.
    • max - Used with scale and min to define the colour scale. If not included, the maximum value of the column will be used.
  • sort - the name of the column to sort by.
  • reverse - (boolean) By default the order is from low to high but you can order from high to low if this is set to true.
  • colours - Define some visualisation-specific named colours.
  • width - An optional minimum width (e.g. 100%) for the table.
  • where - Limit the rows to include
  • attribution - Add a line of attribution text under the visualisation.

1. Simple table§

Embeddable version

This example shows three columns from a CSV file.

This example was made with config:

YAML 
data: test.data.table
columns:
  - name: Overall category
  - name: Intervention
  - name: Sub-category
JSON 
{
	"data": "test.data.table",
	"columns": [{
			"name": "Overall category"
		},{
			"name": "Intervention"
		},{
			"name": "Sub-category"
		}]
}

2. Merge rows§

Embeddable version

Let's tidy up the table a little. Two of the columns contain a number of neighbouring rows that have the same values. We can choose to merge those rows by setting mergerows to true (this will set the rowspan property on the first table cell).

Overall categoryInterventionSub-category
TrainingTraining, up-skilling and re-training/re-skillingPrior learning assessment and recognition (PLAR)
Educational, technical and vocational training (TVET)

			"name": "Sub-category"
		}]
}

3. Colourful columns§

Embeddable version

We can set a colour for a column. The text of those cells will be set to a contrasting colour.

JSON 
{
	"data": "test.data.table",
	"columns": [{

			"colour": "#2254F4"
		},{
			"name": "Intervention",
			"mergerows": true
		},{
			"name": "Sub-category"
		}]
}

4. Virtual columns§

Embeddable version

Sometimes your data source may not be in quite the format you need. We can use template to create a "virtual column" that is a simple string built from values that exist in the data. In this example we generate a column named Local Authority which creates a link using the page and url values. Defining a column with a template is also useful for renaming a column heading. We can also set the text alignment in a column using align.

5. Heat map columns§

We can set a scale (with optional min and max values) for a specific column to colour the numeric cells in that column.

6. Set table width§

No default width is set for tables. If, say, you would like to make a specific table take up 100% of the width of the container you can set the width value.

7. Sort by column§

Embeddable version

If you would like to pre-sort the table by a particular column, you can set sort to the column name. You can also reverse the direction of the sort. Note that sort is applied before mergerows.
