Typo:

[litzinger]

There is a typo in the core table view file:

ExpressionEngine/system/ee/ExpressionEngine/View/_shared/table.php

Line 400 in 335e352

<div class=\"grid-field__column-label__instraction\">

Should be "instruction", not "instraction". The CSS class might need to be updated too, and probably create an alias css name just in case anyone is still referencing the incorrect spelling.
