Question

我认为删除行有效，但删除列按钮无法正常工作。

这是代码的fiddle。谢谢你的帮助。

HTML

<br/>
<button id="css-irow">Row +</button><br/>
<button id="css-drow">Row -</button><br/>
<button id="css-icol">Col +</button>
<button id="css-dcol">Col -</button>

jquery的

$('#css-irow').click(function(){
        $(".ws-css-table-tr:last").clone(false).appendTo('.ws-css-table')
        .find(".ws-css-table-td").text("");
});

$('#css-drow').click(function(){
  $(".ws-css-table-tr:last-child").remove(); 
});


$('#css-icol').click(function(){
    $(".ws-css-table-tr").each(function(i, row){
        $(".ws-css-table-td:last", row).clone().appendTo(row).text("");
    });

$('#css-dcol').click(function(){
 $(".ws-css-table-td:last-child").remove(); 
});

CSS

.ws-css-table {
    display: table;
}
.ws-css-table-tr { 
    display: table-row;     
}
.ws-css-table-td { 
    display: table-cell;
    border:1px solid #000;
    width: 15px;
    height:15px;
    text-align:center;
  vertical-align:middle;
}

试试这个...你的代码有一些问题，包括处理表空的情况。

    CGPoint pointOfInterest = CGPointMake(0.5, 0.5);

    if (mirrored)
    {
        viewCoordinates.x = frameSize.width - viewCoordinates.x;
    }

    if (fillMode == kGPUImageFillModeStretch) {
        pointOfInterest = CGPointMake(viewCoordinates.y / frameSize.height, 1.f - (viewCoordinates.x / frameSize.width));
    } else {
        CGSize apertureSize = CGSizeMake(CGRectGetHeight(frame), CGRectGetWidth(frame));
        if (!CGSizeEqualToSize(apertureSize, CGSizeZero)) {
            CGPoint point = viewCoordinates;

因为你把关闭搞砸了。列删除位于add add列中，因此在添加列之前不会附加click事件。

小提琴：https://jsfiddle.net/x7865gka/6/

$('#css-icol').click(function () {
    $(".ws-css-table-tr").each(function (i, row) {
        $(".ws-css-table-td:last", row).clone().appendTo(row).text("");
    });
});

$('#css-dcol').click(function () {
    $(".ws-css-table-td:last-child").remove();
});
