import numpy as np

from deephaven import dtypes
from deephaven import new_table
from deephaven.column import InputColumn

np_arr = np.array([1, 2, 3], dtype=np.int32)
j_arr = dtypes.array(dtypes.int32, np_arr)
int_arr_col = InputColumn("IntArrCol", dtypes.int32_array, input_data=[j_arr])
t = new_table([int_arr_col])
