Comment 2 for bug 1645862

Bug #1702929 will address this by allowing column configurations to be stored as org unit settings, allowing for org-scoped defaults.

However, it's also possible today to apply default column widths directly in the template by applying a value for the "flex" attribute. The default flex value is "2".

To make a column twice as wide as the default, for example:

<eg-grid-field flex="4" ....></eg-grid-column>
