g.cdpad

[zulu]

Hi,

Can anyone tell me for what g.cdpad is exactly needed?

What is following code snippet from flexigrid.js doing?

g.cdpad = 0;
g.cdpad += (isNaN(parseInt($('div', cdcol).css('borderLeftWidth'))) ?
0 : parseInt($('div', cdcol).css('borderLeftWidth')));
g.cdpad += (isNaN(parseInt($('div', cdcol).css('borderRightWidth'))) ?
0 : parseInt($('div', cdcol).css('borderRightWidth')));
g.cdpad += (isNaN(parseInt($('div', cdcol).css('paddingLeft'))) ? 0 :
parseInt($('div', cdcol).css('paddingLeft')));
g.cdpad += (isNaN(parseInt($('div', cdcol).css('paddingRight'))) ? 0 :
parseInt($('div', cdcol).css('paddingRight')));
g.cdpad += (isNaN(parseInt($(cdcol).css('borderLeftWidth'))) ? 0 :
parseInt($(cdcol).css('borderLeftWidth')));
g.cdpad += (isNaN(parseInt($(cdcol).css('borderRightWidth'))) ? 0 :
parseInt($(cdcol).css('borderRightWidth')));
g.cdpad += (isNaN(parseInt($(cdcol).css('paddingLeft'))) ? 0 :
parseInt($(cdcol).css('paddingLeft')));
g.cdpad += (isNaN(parseInt($(cdcol).css('paddingRight'))) ? 0 :
parseInt($(cdcol).css('paddingRight')));

Is this code superfluous?

Thanks.
