The Kafka config-steams docs includes a table for "Optional Configuration Parameters". The first ("Parameter Name") and last ("Default Value") columns text doesn't wrap around when the text length exceeds the width of the columns. Because of this, some of the text gets hidden from the view.
This is the case with both 2.6.0 as well as 2.5.1 versions and may be others as well. This needs to be handled similar to how the text in third ("Description") column is handled where the text wraps around and all the data is visible.
