HI @bradleysmagacz so this default value will be apply on every columns when data is empty array on BootstrapTable?

Hi @AllenFang, this will actually only apply at object key level. For example, lets say I have an array of objects that look like this:

[{ name: 'Greg', level: 1 }, { name: 'John', level: 2, weight: 180 }]

And let's say the user passes in 'No Data' as the defaultValue prop. When the table renders, Greg's weight will be set to 'No Data' instead of an empty field. If the user does not pass in a defaultValue prop, everything will function as before.

Although it's not a common use case, there are situations in our application where we need to render a default value when the object key does not exist or no data is available.

@bradleysmagacz, I see, thanks your descriptions 👍

HI @bradleysmagacz , after review, I think the defaultValue should be depend on every different TableHeaderColumn, for your above example, weight may have 50 as default, level may have 1 as default and so on, so could you please have me to change for this? If you dont know how to handle it, I can help you, but just let me know, thanks 👍

Hi @AllenFang. How can the defaultValue prop be passed down to TableColumn, where the data value is being rendered, if the prop is being passed into TableHeaderColumn? Currently I only see a way to pass down the defaultValue prop to TableColumn through TableBody.

If I may add something: I'd rather have the default value be a PropTypes.func than a PropTypes.string, so that we can make it work nicely if sorting or filtering is invoked (the value for a cell may be a Date or a number.)

Also: don't you want this default value to be proposed (by default) in the Add Row dialog? (This is what I would understand of a column's default value.)

@bradleysmagacz

1. get the defined on here, this function transfer each props on TableHeaderColumns into an plan object.

2. Actually, I already pass the columns object into TableBody, here, so you can get each columns props data in the TableBody.

3. here render the TableColumn, so you can pass the default value into it.

Let me know if you still have any questions, thanks
