// Simple Sticky Header and Column implementation for HTML tables

// License: MPL 2.0+
|

|
||||
// USAGE:
|
||||
// makeStickyHeaders(table): add sticky header and footer to table
|
||||
// table.parentNode is assumed to be the scroll container
|
||||
// fixStickyRow(table, tr): fix table row (tr) after modifications
|
||||
// fixStickyHeader(table): fix table header after modifications
|
||||
|
||||
// WARNING 1: after using this plugin all columns and rows except 0th ones become shifted by 1.
|
||||
// table.rows[1] and table.rows[*].cells[1] become special invisible rows/cells with copies of first
|
||||
// row and column content inside.
|
||||
|
||||
// WARNING 2: this plugin does NOT support border-collapse because it is implemented by non-integer border
|
||||
// sizes O_o and slightly differently in different browsers which leads to problems calculating cell positions.
|
||||
|
||||
// WARNING 3: all table cells should obviously have non-transparent background
|
||||
// because fixed ones are positioned over normal.
