fix: Display table data when there are periods in string column names

[hydrosquall]

Motivation

• A redo of [bugfix] Update column accessor in Grid component from string property to function accessor. #41 (reverted b/c of integration test) + a test of whether NPM canary deploys via auto are working as intended. Patches adds an extra line to address the integration test that was detected in Add a changelog #55.
• Looked at the Node integration test, realized that a column ID needs to be provided when we use function instead of string accessors (see logs: https://github.com/nteract/data-explorer/runs/2935372040 ).

Testing

• This is the same change as [bugfix] Update column accessor in Grid component from string property to function accessor. #41, with an extra line to fix the integration test issue mentioned previously. A preview deploy of the library can be tested using the sample PR link indicated below.
