dropColumns!(table, colNames)

Alias: drop!

table is a table object. It is an in-memory table or a DFS table (for OLAP engine only).

colNames is a STRING scalar/vector indicating a column name. If table is a DFS table, it must be a scalar.

Delete one or multiple columns from a table. Note that deleting a partitioning column from a DFS table is not supported.

t=table(1 2 3 as x, 4 5 6 as y, 7..9 as z, 10..12 as a, 13..15 as b, 16..18 as c);
t;

t.dropColumns!(`x);

dropColumns!(t, `a`b);
