Summary: User can freeze any number of columns, which will not move when a user scrolls grid horizontally. Main use cases: - Frozen columns don't move when a user scrolls horizontally - The number of frozen columns is automatically persisted - Readonly viewers see frozen columns and can modify them - but the change is not persisted - On a small screen - frozen columns still moves to the left when scrolled, to reveal at least one column - There is a single menu option - Toggle freeze - which offers the best action considering selected columns - When a user clicks a single column - action to freeze/unfreeze is always there - When a user clicks multiple columns - action is offered only where it makes sens (columns are near the frozen border) Test Plan: Browser tests Reviewers: dsagal, paulfitz Reviewed By: dsagal Differential Revision: https://phab.getgrist.com/D2852

|
|
// performance. Problem is: it's impossible to get cursor exactly right with a
|
|
// one-sided border. Attaching a cursor as additional element inside the cell
|
|
// truncates the cursor to the cell's inside because of 'overflow: hidden'.
|
|
// (2) 'div.field' with 'div.field_clip' inside, on which a class is toggled. This
|
|
// works well. The only concern is whether this slows down rendering. Would be
|
|
// good to measure and compare rendering speed.
|
|
// Related: perhaps the fastest rendering would be for a table.
|
|
// (3) Separate element attached to the row, absolutely positioned at left
|
|
// position and width of the selected cell. This works too. Requires
|
|
// maintaining a list of leftOffsets (or measuring the cell's), and feels less
|
|
// clean and more complicated than (2).
|
|
|
|
// IsRowActive and isCellActive are a significant optimization. IsRowActive is called
|
|
// for all rows when cursor.rowIndex changes, but the value only changes for two of the
