Column merging investigation

+Empty columns is a column that has no originating cells +

Table standard discusses this under "track merging".

+ +

Compatibility

+
  • Edge17 has a bug where width of a colspanned cell always includes cell width + width of border spacing. It should be max(cell width, border spacing)
    • +
  • Safari matches Chrome Legacy. TD-originated columns are always merged.
    • +
  • Firefox follows the standard, but has a few bugs.
    • +
    + +

    TD merging

    + +
    Auto table, and TD.colspan=10
+  FF/Chrome Legacy/Safari: Standard. Tracks merge.
+  Edge17: Tracks do not merge. Wide cell is 180px (9 * border spacing)
+
    + + + + + + + + + + +
    auto
    + +
    Auto table(400px), and TD.colspan=10
+  FF/Chrome Legacy/Safari/Edge17: Standard. Tracks merge. Colspan cell grows because it is unconstrained.
+
    + + + + + + + + + + +
    auto 400px
    + +
    Auto table(130px), and TD.colspan=10
+  FF/Chrome Legacy/Safari: Standard. Tracks merge. Colspan cell shrinks to min width becuase it is unconstrained.
+  Edge17: Non-compliant, buggy. Wide cell too wide, narrow cell disappears.
+
    + + + + + + + + + + +
    auto 130px
    + +
    Fixed(400px) table, and TD.colspan=10
+  Chrome/Safari: Non-compliant. Tracks merge. Cells are the same size, fixed algo distributes extra width evenly.
+  Firefox: Standard.
+  Edge17: Standard, buggy. Wide cell too wide. Edge's bug is that it computes max width as (width + border_spacing) instead of max(width, border_spacing).
+
    + + + + + + + + + + +
    fixed 400px
    + +
    Fixed(130px) table, and TD.colspan=10
+  Chrome/Safari: Non-compliant.Tracks merge, cells same size.
+  Firefox: Standard + buggy. Table does not grow.
+  Edge17: Standard + buggy. Wide cell too wide.
+
    + + + + + + + + + + +
    fixed 130px
    + +

    COL merging. Same tests with COL span=10 replacing TD

    + +
    Auto table
+  FF/Chrome Legacy/Safari, Edge17: Standard. wide cell is 50px, tracks do merge.
+
    + + ++ + + + + + + + +
    auto
    + +
    Auto table(400px)
+  FF/Chrome Legacy/Safari, Edge17: Standard. Both cells grow the same because unconstrained.
+
    + + ++ + + + + + + + +
    auto 400px
    + +
    Auto table(130px)
+  FF/Chrome Legacy/Safari, Edge17: Standard. Both cells shrink.
+
    + + ++ + + + + + + + +
    auto 130px
    + +
    Fixed(400px) table
+  Chrome/Safari,Firefox: Standard.
+  Edge17: Buggy. Fixed cells grow to fill table.
+
    + + ++ + + + + + + + +
    fixed 400px
    + +
    Fixed(130px) table
+  Chrome/Safari: Standard, very buggy. Non-collapsed columns shrink to single border spacing.
+  Firefox: Standard.
+  Edge17: Non-compliant, collapses columns.
+
    + ++ + + + + + + + + +
    fixed 130px
    + +

    COL merging when COL has specified width.

    + +
    • Chrome Legacy/Edge17/Safari: non-compliant, merge COLs with specified widths. +
    • Firefox: Standard, unless COL width is 0px. Buggy, does not include border-spacing around columns.
    +
    Auto table, COL width 30px.
+  Chrome Legacy/Edge17/Safari: non-compliant, merge.
+  Firefox: Standard, buggy. does not include border-spacing around columns.
+
    + + ++ + + + + + + + +
    auto col 30px
    + +
    Auto table, COL width 5%.
+  Chrome Legacy/Edge17/Safari: non-compliant, merge.
+  Firefox: Standard, buggy. does not include border-spacing around columns.
+
    + + ++ + + + + + + + +
    auto col 10%
    + +
    Auto table, COL width 0px.
+  Everyone: merges COL
+
    + + ++ + + + + + + + +
    auto col 0px
