To have multiple attributes or generally data items within the cells of a given
column, flex-table-card provides multi as a cell content matcher.
As to be seen in the following listing, the yaml notation is by far not pretty
due to the needed list-of-list-of-(2)-strings within multi. yaml in fact
supports both notations, but mostly converts to the first one, converting it to
not-really-human-friendly.
type: 'custom:flex-table-card'
title: Power Consumption (Top 10)
entities:
include: 'sensor.*_energy(_[0-9]+)?'
columns:
- attr: node_id
name: NodeID
- attr: power_consumption
name: Power
- name: Energy
prop: state
- name: My Multi-Item-Field
# the default 'multi_delimiter' is a whitespace: ' '
multi_delimiter: ','
# match 'attr: node_id', 'attr:power_consumption' and 'prop:state' into each
# cell and concat all using the previously defined: 'multi_delimiter'
multi:
- - attr
- node_id
- - attr
- power_consumption
- [prop, state]
