             Summary: Option to disable auto-formatting and type detection in table displays
                 Key: ZEPPELIN-1760
                 URL: https://issues.apache.org/jira/browse/ZEPPELIN-1760
             Project: Zeppelin
          Issue Type: Wish
          Components: front-end, GUI
    Affects Versions: 0.6.2
            Reporter: Everett Anderson


Support disabling auto-format/type detection of table displays.

ZEPPELIN-1371 added auto-format/type detection table displays. For example, when Zeppelin believes a given column contains numbers (even if it were, say, a Spark DataFrame string column) it displays these in the UI with commas.

However, this can be misleading in some workflows. For example, when using Zeppelin to evaluate a table produced by an extraction pipeline for a fixed-width or CSV file, it can be important to know how many characters were in the field. Maybe more commonly, sometimes columns are not numbers but codes.

It'd be great to have the ability to configure column type detection and display format.

Disabling automatic type detection/format globally or per interpreter in configuration would be a first step. At the moment, I don't believe there's a way to see the "true" column values in a table.
