Merging Blink Commit:

columnMaxLogicalWidth = std::max(columnMaxLogicalWidth, columnMinLogicalWidth);
                    m_layoutStruct[pos].effectiveMaxLogicalWidth = std::max(m_layoutStruct[pos].effectiveMaxLogicalWidth, columnMaxLogicalWidth);

Here: https://github.com/WebKit/WebKit/blob/2eed0466d7087a67e3b65404c23d3e1622e6ae15/Source/WebCore/rendering/AutoTableLayout.cpp#L430

It does not progress below test case though, we might have other issue in handling colspan, which we might need to fix before doing this.
