Use Overrides. Open Overrides and select the field you wish to implement the data links, add override property “Data Links”. Add a new data link and enter a full URL (with the http/s) to redirect to another site OR just add a suburl since it will append with the grafana’s URL. Use the data variable ${__value.raw} to substitute the value with the values from the current cell.
In any case if you want to do a link but the value doesnt match how the link should be (value with spaces etc) you can use transformation, hide the column that contains the transformed value using overrides, and use ${__value.text} instead.
