<zk>
    <style>
        .columns-noshrink .z-column {
            flex-shrink: 0!important;
        }
    </style>
    1) hflex="1" column shrinking down to 0
    <grid>
        <columns>
            <column label="column-1" width="200px"/>
            <column label="column-2" hflex="1"/>
            <column label="column-3" width="200px"/>
        </columns>
        <rows>
            <row>
                <cell>content-1</cell>
                <cell>content-2</cell>
                <cell>content-3</cell>
            </row>
        </rows>
    </grid>
    2) after applying a min-width the  FIXED columns shrink
    <grid>
        <columns>
            <column label="column-1" width="200px"/>
            <column label="column-2" hflex="1" style="min-width: 200px"/>
            <column label="column-3" width="200px"/>
        </columns>
        <rows>
            <row>
                <cell>content-1</cell>
                <cell>content-2</cell>
                <cell>content-3</cell>
            </row>
        </rows>
    </grid>
    3) workaround disable column shrinking
    <grid sclass="columns-noshrink" >
        <columns>
            <column label="column-1" width="200px"/>
            <column label="column-2" hflex="1" style="min-width: 200px"/>
            <column label="column-3" width="200px"/>
        </columns>
        <rows>
            <row>
                <cell>content-1</cell>
                <cell>content-2</cell>
                <cell>content-3</cell>
            </row>
        </rows>
    </grid>
