calculateWidths()
    calculate total table width based on intrinsic size 
        and enclosing  block
    count total columns based on top row
    create column width array
    for each cell in top row
        for each cell col span
            col_width[i] = cell.width/cell.col_span
        col_width[i] = cell
        if cell spanned
            col_width[i+] width = -1
    count unset columns
    distribute remaining space among columns

rendering step
TableBox Table.calculateBoxes()
    TableBox = new TableBox()
    create and add title box to table
    create and add header box to table
    for each row
        for each cell
            create cellbox
            layout contents of the cell
            box.w = cell.getWidth()
            box.h = cell.getHeight()
            box.x = table.getColumnX(cell.getColumn())
            box.y = table.getRowY(cell.getRow())
            add box to table
    create and add footer box to table
    create and add caption box to table
    
==============

plan

//implement table and table layout 2
--- width calculations
//test with one row of cells and explicit width for table
//test with one row of cells with explict width on the cells
//test with top row one fixed and one auto
//test with two rows of cells with w/ on table
//test with two rows of cells with w/ on top cells
--- col spans
//test with two rows of cells with col span on bottom
//test with two rows of cells with col span on top
//test with three rows of cells with second row span at end
//test with three rows of cells with second row span at beginning
--- row spans
test with two rows of cells with row span at end
test with two rows of cells with row span at beginning
--- test spacing
test w/ spacing = 10 and 3x3 grid of auto cells
test w/ spacing = 10 and 3x3 grid of fixed cells
--- table headers
//add support for table headers (th)
--- extra boxes
research header/footer/caption/title stuff
--- extents
does table support padding? if not,
test 2x2 auto w padding = 0
test 2x2 auto w padding = 10
test 2x2 fixed w padding = 10

future stuff
collapsing borders model vs separated borders model
add a caption
support using the thead, tbody, and tfoot elements
align the caption
table style layout on non-table elements
support hiding the empty cells
support sizing the cells to the grid, instead of to the contents,
    if contents are smaller
