I'm working on a data cleaning feature. In this feature, users are required to assign each columns in a dataset be an input or an output. Optionally, users will be able to rename columns, ignore columns and view a histogram.

To do this, I have developed an initial mockup which has a table that has a column to display column names and a second column for column type. Third columns for renaming. At the top, I have a bulk action button for assigning multiple inputs/outputs.

Problem: We cannot display the histogram for each column on load because that would take a long time, so we only load one at a time. The issues is that it's difficult to keep track of the column in the table while viewing the histogram below it. Is there a better way to display the histogram?
