Angular Data GridComments

Add a comment (a note) to a cell, using the context menu, just like in Excel. Edit and delete comments. Make comments read-only.

Enable the plugin
Add comments via the context menu
Set up pre-set comments

Enable the plugin

Set the comments configuration option to true to enable the feature and add all the needed context menu items. For example:

data = [
  ["A1", "B1", "C1"],
  ["A2", "B2", "C2"],
];
settings = {
  comments: true,
};

<hot-table [data]="data" [settings]="settings" />

After you've enabled the plugin, the Context Menu gains a few new items:

Add/Edit comment
Delete comment
Read-only comment

Set up pre-set comments

You can also pre-define comments for your table. Comments are stored in the table's/column's/cell's metadata object and you can declare as any value of the respective type. For example:

settings = {
  cell: [{ row: 1, col: 1, comment: { value: "Hello world!" } }],
};

In this example, the comment "Hello world!" is added to the cell at (1,1).

By default, all comments are editable. To change this, set the readOnly configuration option to true when adding a comment. This example makes the "Tesla" comment attached to a cell read-only, whereas the "Honda" comment attached to another cell is editable.
