columns

The columns method returns all of a Table's column definitions, as a list of Column objects.

Syntax​

source.columns -> list

Parameters​

This method takes no arguments.

Returns​

A list of all of the Table's column definitions.

Example​

Here, we create a table and a time table, and print their lists of column definitions with two calls to table.columns.

from deephaven import new_table, time_table
from deephaven.column import string_col

source = new_table(
    [
        string_col("Title", ["content"]),
        string_col("ColumnName", ["column_content"]),
        string_col("AnotherColumn", ["string"]),
    ]
)

tt = time_table("PT1S")

print(source.columns)
print(tt.columns)
