[hushengbin789]

Table表格新增最小高度min-height，方便使用最小高度
props: { minHeight: { type: [Number, String] } }
computed-->styles
styles () { let style = {}; if (this.height) { const height = parseInt(this.height); style.height =${height}px; } if (this.maxHeight) { const maxHeight = parseInt(this.maxHeight); style.maxHeight = ${maxHeight}px; } if (this.minHeight) { const minHeight = parseInt(this.minHeight); style.minHeight = ${minHeight}px; } if (this.width) style.width = ${this.width}px; return style; },
computed-->bodyStyle
bodyStyle () { let style = {}; if (this.bodyHeight !== 0) { const height = this.bodyHeight; if (this.height) { style.height =${height}px; } else if (this.maxHeight) { style.maxHeight = ${height}px; } else if (this.minHeight) { style.minHeight = ${height}px; } } return style; }
computed-->toggleExpand
`
