Unable to delete rows in input tables when key columns are not the first columns

[mofojed]

Description

If you specify an input table where the key columns are not the first columns in the table, you cannot delete rows.

Steps to reproduce

1. Execute the following snippet:

from deephaven import empty_table, input_table

_source1 = empty_table(5).update(["Strings=`A` + i", "Integers=i"])
_source2 = empty_table(5).update(["Integers=i", "Strings=`A` + i"])

result1 = input_table(init_table=_source1, key_cols="Strings")
result2 = input_table(init_table=_source1, key_cols="Integers")
result3 = input_table(init_table=_source2, key_cols="Strings")
result4 = input_table(init_table=_source2, key_cols="Integers")

2. In each resultN table, right-click a row and select "Delete Selected Rows"

Expected results
2. Should be able to delete a row in each table

Actual results
2. Cannot delete a row in result2 and result3 (when the key columns are not the first column). Error message in console:
