数据模型dataModel遍历图元时并且要移除指定时，不能在遍历循环中dm.remove()，需要做好标记在新的循环中移除，否则会影响前面循环遍历本身!

JavaScript
let toberemoved = []
cache.table.getColumnModel().getDatas().forEach((child,index) =>{
    if(index < data.ca('columnWidths').length) {
        console.log(cache.table.getColumnModel().getDatas())
        child.setWidth(data.ca('columnWidths')[index]);
    }
    if(index < nodeData.ca('columns').length){
        let columnData = nodeData.ca('columns')[index]
        columnData.displayName && child.setDisplayName(nodeData.ca('showColumnIndex') ? index + ':' + columnData.displayName : columnData.displayName)
        child.setAlign(data.ca('centerAlign') ? 'center' : 'left');
        //单元格字体及颜色
        let defaultColor = nodeData.ca('tableTextColor')[1];
        child.getLabelColor = (value, data, state)=>{
            if(value){    //data.getId() == 2 && index == 1，指定某行某列的字体颜色！
                let cb = new Function('return ' + nodeData.ca('columnDataFunc'))()
                let ret = cb && cb(nodeData,data,child,index,value)
                let colortmp = ret ? ret : defaultColor;
                return colortmp;
            }
            else{
                return defaultColor;
            }
        }
    }else{
        //记录需要被移除的图元，注意不能直接在这里移除，会影响未完成的循环！
        toberemoved.push(child);
    }
})

//根据标记移除图元
toberemoved.forEach((child,index)=>{
     cache.table.getColumnModel().remove(child);
})
