Table resize does not work well when there is colpsan

[JiuqingSong]

<table style="box-sizing: border-box; border-collapse: collapse; border-spacing: 0px;"><tbody><tr><td colspan=2 style="width: 124px; height: 22px; border-width: 1px; border-style: solid; border-color: rgb(171, 171, 171); box-sizing: border-box;"><br></td><td style="width: 108px; height: 22px; border-width: 1px; border-style: solid; border-color: rgb(171, 171, 171); box-sizing: border-box;"><br></td></tr></tbody></table>

Resize this table column, depends on where to drag, it may not moving, or move some other cell.

This is because the colspan attribute causes table cell index mismatch with the index of width array.

We should always use the correct column/row index
