Table view and grid system

[himself65]

Currently, our data structure will or may limit the grid system or database block implementation. Why? Our infra code is a tree structure that each model holds its children. This may affect the code spec of the drag handle (seachBinary part by @fundon), and the way to make the tree into one depth array.

A draft design of the RowBlock:

Based on this design, it's possible that we support GridBlock in a similar way (having the grid container that holds the columns, rather than on the database).

In this case, the outer DatabaseBlock won't have columns. This blurs the boundary between DatabaseBlock and GridBlock. In this case, essentially we only need a ContainerBlock that holds either:

• ContainerBlock[], in this case, the parent container is used for layout.
• ContentBlock[], in this case, the parent container is used for column-and-tag-based view.

Within DatabaseBlock, there is its own drag-and-drop behavior, such as row, column dragging, etc. As well as it supports only simple primitive types.

In the context of a document, it is like any other block, the whole DatabaseBlock can be dragged freely. But other blocks cannot be dragged into the DatabaseBlock unless the DatabaseBlock supports advanced data types.

If other types of blocks are to be dragged into the DatabaseBlock, a type(block) conversion is required.

And another difference is we don't hold a cell in the database. it's an attribute(tag) for a block. That makes sense if you drag a row into another database or under the frame block. The attribute won't disappear because it's saved in the top-level of page

Interesting.

Another small question is the concept of having a reference block, links a link.

I wouldn't want to drag a block anywhere, I'd just reference it, click it and then jump or expand it.

[himself65]

The reference is not in discussion, but I can say that we would have a single Y.Doc to keep all blocks that would be shared in many docs, called Gallary.

In our infra, if you want to make a block to be referenced in many docs, first we will put the block into Gallary, then add a reference block(like a pointer)

Thanks for the answer. :)
