Two-way table of covariate-effects
A two-way table of covariate-effects consists of effects of the entries (the row factor in the two-way table) on a target trait in each environment (the column factor in the two-way table). Do not confuse this with a two-way table of measured values such as a genotype-by-environment two-way table of yield or a genotype-by-trait table in an environment or across environments.
The most typical example is a table that contains the effects of a number of QTL (rows) in a number of environments (columns).
