微信小程序:实现多功能表格效果,例如滚动效果、宽度自定义、多选、行内编辑等功能

一、表格效果

1、实现功能

表格实现可横向水平滚动表格、宽度自定义、文本编辑、数字加减、多选,行选中效果,获取选中行数据等功能

2、图片效果

 

二、代码

1、wxml

根据头循环将表格头进行循环,再通过昂循环展示行内的全部信息,根据数组width索引,去调整每一行的宽度,根据三目运算实现行的选中效果

<view class="main">
  <view class="table">
    <scroll-view class="scroll" scroll-y scroll-x>
      <view class="header">
        <view class="header_item" wx:for="{{header}}" wx:key="index" style="width: {{width[index]}};">
          {{item}}
        </view>
      </view>
      <view class="content">
        <view class="content_line {{dataItem.checked ? 'selected-row' : ''}}" wx:for="{{list}}" wx:key="index" wx:for-item="dataItem">
          <view class="content_item" style="width: {{width[0]}};">
            <checkbox checked="{{dataItem.checked}}" bindtap="handleCheckboxChange" data-index="{{index}}" />
          </view>
          <view class="content_item" style="width: {{width[1]}};">{{dataItem.date}}</view>
          <view class="content_item" style="width: {{width[2]}};">{{dataItem.number}}</view>
          <view class="content_item" style="width: {{width[3]}};">
            <input type="text" value="{{dataItem.person}}" bindinput="handlePersonInput" data-index="{{index}}" class="input-text" />
          </view>
          <view class="content_item" style="width: {{width[4]}};">{{dataItem.item_no}}</view>
          <view class="content_item" style="width: {{width[5]}};">{{dataItem.item_name}}</view>
          <view class="content_item" style="width: {{width[6]}};">{{dataItem.sub_loc}}</view>
          <view class="content_item" style="width: {{width[7]}};">{{dataItem.wait_qty}}</view>
          <view class="content_item" style="width: {{width[8]}}; ">
            <view class="btn" bindtap="handleNowQtySubtract" data-index="{{index}}">-</view>
            <input type="number" value="{{dataItem.now_qty}}" bindinput="handleNowQtyInput" data-index="{{index}}" class="input-number" />
            <view class="btn" bindtap="handleNowQtyAdd" data-index="{{index}}">+</view>
          </view>
          <view class="content_item" style="width: {{width[9]}};">
            <view class="btn" bindtap="handleRejectQtySubtract" data-index="{{index}}">-</view>
            <input type="number" value="{{dataItem.reject_qty}}" bindinput="handleRejectQtyInput" data-index="{{index}}" class="input-number" />
            <view class="btn" bindtap="handleRejectQtyAdd" data-index="{{index}}">+</view>
          </view>
        </view>
      </view>
    </scroll-view>
  </view>
  <view class="footer">
    <button bindtap="getSelectedData">获取选中的数据</button>
  </view>
</view>

2、wxss

page {
  background-color: #f8f8f8;
}

.table {
  width: 100%;
}

.input-text {
  border-bottom: 1px solid #4eade4;
  text-align: center;
}

/* 多选框样式 */
checkbox {
  display: flex;
  justify-content: center;
  align-items: center;
}

/* 按钮样式 */
.footer {
  margin-top: 20px;
  text-align: center;
}

button {
  width: 200px;
  background-color: #4bb6e7;
  color: white;
  border-radius: 5px;
}

.scroll {
  overflow: hidden;
  background: white;
  width: 100%;
}

.header {
  display: grid;
  grid-auto-flow: column;
  font-size: 26rpx;
  font-weight: bold;
  color: #292929;
}

.header_item {
  display: flex;
  align-items: center;
  justify-content: center;
  text-align: center;
  background: #80d3f8;
  width: 150rpx;
  height: 60rpx;
  border: 1rpx solid #98a5ab;
  border-left: 0;
  border-top: 0;
}

.content {
  background-color: #fff;
}

.content_line {
  display: flex;
  flex-wrap: nowrap;
  width: max-content;
  border-bottom: 1px solid #eee;
}
/* 选中行样式 */
.content_line.selected-row {
  background-color: #d7edff;
  border-radius: 5px;
}
.content_item {
  width: 150rpx;
  height: 60rpx;
  display: flex;
  align-items: center;
  justify-content: center;
  border: 1rpx solid #98a5ab;
  border-left: 0;
  border-top: 0;
  font-size: 85%;
  word-break: break-all;
}

.header_item:nth-child(1),
.content_item:nth-child(1) {
  border-left: 1rpx solid #98a5ab;
}

.input-number {
  width: 35px;
  text-align: center;
}

.btn {
  width: 25px;
  height: 20px;
  margin: 0 2px;
  padding: 0;
  font-size: 12px;
  line-height: 20px;
  text-align: center;
  background-color: rgb(96, 178, 226);
}

3、js

首先定义变量:头、宽度、行数据

处理多选功能、多选选中数据获取功能、文本输入功能、加减功能等

Page({
  data: {
    header: ['选择','日期', '单号', '人员', '料号', '名称', '储位', '待发', '本次发', '拒绝'],
    width: ['50px','50px', '100px', '50px', '100px', '100px', '50px', '50px', '100px', '100px'],
